Upgrade issues

Date filed Issue number Description
2023-09-12 SPL-244559, SPL-245880, SPL-246158 Upgrades of Splunk Enterprise to version 9.1.x can fail on machines that run an operating system that does not use Unicode Transformation Format - 8 bit (UTF8) character set encoding.

Workaround:
This notice previously applied to Windows Server using the Japanese system locale. It now applies to any operating system that does not use UTF-8 for character set encoding.

Prior to an upgrade, edit the $SPLUNK_HOME/etc/splunk-launch.conf file (%SPLUNK_HOME%\etc\splunk-launch.conf on Windows) and add the following line:

PYTHONUTF8=1

Save the file, then perform the upgrade.

If the upgrade succeeds, but Splunk Web then displays a blank screen when you attempt to log into the Splunk Enterprise instance, follow this workaround, then restart the Splunk Enterprise instance.

2020-11-09 SPL-197140, SPL-234386 UF failed to start on Solaris 11.3 with error: "symbol in6addr_any: referenced symbol not found"

Workaround:
1. Do not upgrade past Splunk 8.0.5 on Solaris 11.3

OR 2. Upgrade to Solaris 11.4

2020-08-31 SPL-194426 External search command chunked v2 python SDK fails with multibyte result data under python 3.

Workaround:
Apps may experience this issue if they: implement a custom search command using the Splunk Enterprise SDK for Python between versions 1.6.5 and 1.6.13; are executed by Splunk Enterprise or Splunk Cloud using Python 3; and are sent events with multi-byte characters.

App developers whose apps implement a custom search command using a version of the Splunk Enterprise SDK for Python must update to version 1.6.14 or higher and release new versions of their apps.

Splunk Enterprise and Splunk Cloud administrators who are using apps impacted by this issue must update to app versions that use the Splunk Enterprise SDK for Python version 1.6.14 or higher. If this is not possible, administrators are encouraged to either: allow these apps to be executed using Python 2; or cease usage of impacted apps until updated versions are available.

2020-07-10 SPL-191850 The .deb installation package will fail if dpkg version doesn't support an .xz compressed control file.

Workaround:
Update dpkg to version 1.17.6 or later.
2018-04-13 SPL-153403 After running the "clean userdata" command, admin is unable to login with msg "No users exist. Please set up a new user."

Workaround:
Create a $SPLUNK_HOME/etc/system/local/user-seed.conf and restart Splunk

Data input issues

Date filed Issue number Description
2024-01-13 SPL-249543, SPL-251748, SPL-251749, SPL-253929, SPL-251746, SPL-253927, SPL-253928 TcpInputProcessor not able to drain splunktcpin queue during graceful shutdown.

Workaround:
Splunk recommends customers set `useACK` to true to ensure in-memory is not dropped in the event of indexer rolling restarts or repaving. Thus, the best short-term solution is to set `useACK` to `true`.
2024-01-10 SPL-249424, SPL-249409 Splunk UF (windows) huge amount of duplicating logs due to re-reading log file after Upgrade to 9.1.0.1

Workaround:

Workaround:
Avoid to restart if queue is blocked. (wish maybe should be best practise but the revert is what always happen customer queue blocked let restart to solve it .)

Search issues

Date filed Issue number Description
2024-05-14 SPL-255737 Version 2 of the stats command can't distinguish prestats and non-prestats data in summary index at the event level.
2023-09-27 SPL-245135, SPL-245127 Indexer Search crash with no back-trace in PCRE2 on X86_64

Workaround:
Re-running the search is the only workaround.

This issue is not deterministic within a search, so re-running will usually work.

2023-09-25 SPL-245076, SPL-225303, SPL-245054 Segfault in BucketSummaryActorThread, originating in the lookup processor, causes crashing search processes for Data Model Accelerations

Workaround:
Update the `max_memtable_bytes` in my the limits.conf/[lookup] stanza to a large value, such as 2147483648 (2GB), to increase the threshold at which lookup tables are indexed to disk on the indexers instead of using in-memory indexes for those lookups.

We recommend sizing the threshold based on lookups in your environment.

Please note that this will increase the amount of memory used for searches that use lookups, which could be significant in environments with many concurrent searches.

2023-06-28 SPL-241609, SPL-227018 In rare cases in some buckets, searches can return some empty field values or missing events for indexed fields when the bucket contains small metadata files (between 4-8KB) leading to "not all cwpairs were found" in search.log

Workaround:
Within search.log in the dispatch directory of a failed search, look for the term "not all cwpairs found". If this is found, upgrade to a version that fixes the issue.
2023-04-26 SPL-239409 The 'sendemail' command no longer honors the field order from search results
2023-04-14 SPL-238738 Federated Search for Splunk does not support the "Show Source" Field Action
2023-03-28 SPL-237902 Ad hoc searches that specify earliest relative time offset assuming from 'now' should explicitly include 'latest=now' to avoid a potential time range inaccuracy

Workaround:
Ad hoc searches searches that use the earliest time modifier with a relative time offset should also include 'latest=now' in order to avoid time range inaccuracies. For example, if you want to get all events from the last 10 seconds starting at 01:00:10, the following search returns all events that occur between the time of 01:00:00 and 01:00:10, as expected.

index=main earliest=-10s latest=now

Running the same search without including 'latest=now' might produce unpredictable results or impact performance in certain scenarios when the search head is overloaded with ad hoc searches. See Specify earliest relative time offset and latest time in ad hoc searches in the Splunk platform Search Manual.

2022-10-31 SPL-232219 Resolve event count issues for Tstats in Standard mode when append=true
2022-10-24 SPL-231946, SPL-233842, SPL-233843 |metadata command ignores splunk_server parameter

Workaround:
Use other search commands like |tstats instead of |metadata if you need to filter on splunk_server
2022-10-20 SPL-231830, SPL-239319, SPL-239320 SearchJob sometimes fails and returns error "Search <ID> not found. The search may have been cancelled while there are still subscribers"

Workaround:
Remark : this Splunk Enterprise issue may impact ITSI UI with loading issues (KPI and thresholds preview, Share Base search validation, Entity import, Maintenance windows preview)

Fix : upgrade Splunk to a fixed version

2022-09-26 SPL-230682 Tstats returns incorrect event counts when using append=true
2022-09-23 SPL-230581, SPL-227411 After upgrade one set of clustered indexers has increase in thread crashes during search
2022-09-13 SPL-230091, SPL-231852 Search can use large amount of memory on large/malformed events that (look like) XML
2022-09-12 SPL-229969, SPL-230549, SPL-230857, SPL-230859 regex doesn't honor the caret symbol ^ (start of string) in some conditions.
2022-09-08 SPL-229882 Job inspector can no longer show search logs when the logs are titled search.log.1, search.log.2, etc.

Workaround:
Retrieve the log file from the filesystem. The search's dispatch directory is located at $SPLUNK_HOME/var/run/splunk/dispatch/<sid>. Dispatch directories can also be collected in a Splunk Diag if the search's time-to-live (TTL) has not yet expired.
2022-08-29 SPL-229278 Search crashes with "StatsBuffer found inconsistent row" after upgrading

Workaround:
Use '| noop feature_flag=stats:allow_stats_v2:false' in a search to use StatsV1 to avoid this issue for a single search. Alternatively, add '[stats] use_stats_v2 = false' in the limits.conf file to globally configure this setting for all searches.

Both workarounds impact the performance for searches using the 'stats' family of functions such as 'chart', 'timechart', 'eventstats', 'tstats', 'prestats', 'mstats' and 'streamstats' because performance enhancements added with StatsV2 are not used. As a result, upgrading to Splunk Enterprise version 9.0.1 or higher is preferred.

2022-08-02 SPL-227728, SPL-226351 Mcatalog subsearch hitting maxout limit preventing metric rollup from populating results correctly.
2022-07-29 SPL-227633 Error : Script execution failed for external search command 'runshellscript'

Workaround:
The setting precalculate_required_fields_for_alerts=0 can be set on saved searches that have no other alert actions attached aside from the "Run A Script" action, to quash the error. For saved searches that have multiple alert action attached, this may not be safe as it will disable back propagation of required fields for all alert actions, which might result in the parent search extracting more fields than required, which could negatively impact performance for that search.
2022-07-28 SPL-227547 Fix hash algorithm for numbers and handle hash collisions for lookups

Workaround:
Add

allow_caching=f to the lookup command:

| lookup <name> allow_caching=f ... 

On 7.3+: Add allow_caching=f to the lookup definition on the search head

transforms.conf:
[<lookup name>]
allow_caching = f

To check if you might be running into this issue, you'll need to enable debug on the search in question by adding:

| noop log_DEBUG=CachedProvider
<pre>
If you have hits for the cached lookup, like in the sample log below, you can hit this issue.

<pre>
DEBUG CachedProvider - Cached provider metrics: lookup=<lookup name> hits=67064 misses=321 total=67385
2022-06-23 SPL-226021, SPL-224456 stash_new files for apps using summary indexes, like ITSI, are not being deleted from splunk/var/spool/splunk because TailReader is hung

Workaround:
restart the search head

clears the stash_new files

2022-06-23 SPL-226017, SPL-176333 Lookups may return incorrect results due to internal caching

Workaround:
Add

allow_caching=f to the lookup command:

| lookup <name> allow_caching=f ... 

On 7.3+: Add allow_caching=f to the lookup definition on the search head

transforms.conf:
[<lookup name>]
allow_caching = f

To check if you might be running into this issue, you'll need to enable debug on the search in question by adding:

| noop log_DEBUG=CachedProvider
<pre>
If you have hits for the cached lookup, like in the sample log below, you can hit this issue.

<pre>
DEBUG CachedProvider - Cached provider metrics: lookup=<lookup name> hits=67064 misses=321 total=67385
2022-06-21 SPL-225955, SPL-223099 Job completion emails aren't received while sending the job to background
2022-05-25 SPL-224816, SPL-232036, SPL-232477 Standard mode federated searches of accelerated data models with 'tstats' fail or produce unexpected behavior when 'prestats=t'

Workaround:
possibly:

- run the search in the right order

2021-12-21 SPL-216787 Searches are cancelled or time out when the user leaves the browser window or switches tabs.

Workaround:
In Splunk Enterprise 8.1.7, 8.2.4, and higher change the job_default_auto_cancel setting in $SPLUNK_HOME/etc/system/local/web.conf from the default value of 30 to 62.

Details
This issue is caused by power saving settings in recent browser versions, where Javascript timers may be throttled. The user typically sees the following message in the search window on foreground searches:

DAG Execution Exception: Search has been cancelled
Search auto-canceled
The search job has failed due to an error. You may be able to view the job in the Job Inspector

2021-09-22 SPL-212495, SPL-196040, SPL-219811 Excessive logging 'WARN SearchResultsFiles Unable to parse site_label, label=invalid due to err="Invalid site id: invalid"' for SearchResultsFiles

Workaround:
none
2021-03-08 SPL-202077, SPL-176333 Lookups may return incorrect results due to internal caching

Workaround:
Add

allow_caching=f to the lookup command:

| lookup <name> allow_caching=f ... 

On 7.3+: Add allow_caching=f to the lookup definition on the search head

transforms.conf:
[<lookup name>]
allow_caching = f

To check if you might be running into this issue, you'll need to enable debug on the search in question by adding:

2021-02-25 SPL-201628 `srchTimeWin` and `srchTimeEarliest` settings cannot be unset for the admin role.

Workaround:
Ensure that the admin role is not configured as "Unset" and is explicitly configured to either no restriction or a restriction in the UI (Navigate to Edit Role > Resources > Role search time window limit), or through conf file authorize.conf under attribute name srchTimeEarliest.
2020-12-06 SPL-198314, SPL-233681, SPL-233762 Exporting _time field applies user timezone offset but contains the server's timezone (usually +0000)

Workaround:
Force a specific time format by using strftime in an eval command.

for example, add

 | convert timeformat="%FT%T.%3Q%z" ctime(_time)

to the end of your search

2020-12-04 SPL-198284, SPL-231587 Crash in search process in PrecacheUsersThread when max_searches_per_process is set lower than default

Workaround:
Set limits.conf back to default, by removing any override of max_searches_per_process.

For example:

[search]
max_searches_per_process=1

to

[search]
2020-08-31 SPL-194426 External search command chunked v2 python SDK fails with multibyte result data under python 3.

Workaround:
Apps may experience this issue if they: implement a custom search command using the Splunk Enterprise SDK for Python between versions 1.6.5 and 1.6.13; are executed by Splunk Enterprise or Splunk Cloud using Python 3; and are sent events with multi-byte characters.

App developers whose apps implement a custom search command using a version of the Splunk Enterprise SDK for Python must update to version 1.6.14 or higher and release new versions of their apps.

Splunk Enterprise and Splunk Cloud administrators who are using apps impacted by this issue must update to app versions that use the Splunk Enterprise SDK for Python version 1.6.14 or higher. If this is not possible, administrators are encouraged to either: allow these apps to be executed using Python 2; or cease usage of impacted apps until updated versions are available.

2020-02-12 SPL-183259 When generating LISPY for field values that are numbers (""), the values aren't deduplicated, which can cause slowdowns in certain scenarios

Workaround:
Dedup values in search before, for example:

instead of

index="field_test" [search index="field_test" globalCallID_callId=1234* | fields globalCallID_callId]

add a stats or dedup in the subsearch:

index="field_test" [search index="field_test" globalCallID_callId=123* | stats values(globalCallID_callId) AS globalCallID_callId | mvexpand globalCallID_callId ]

If that list is still large and you're seeing the slowdown, consider moving the filtering to a | where after the initial search, for example:

index="field_test" globalCallID_callId=* | where [search index="field_test" globalCallID_callId=123* | stats values(globalCallID_callId) AS globalCallID_callId | mvexpand globalCallID_callId ]
2020-01-10 SPL-181573 geostats provides incorrect results for lower zoom levels when split BY has a higher cardinality than globallimit.

Workaround:
- Increase globallimit to the value of "unique values" number mentioned in the warning message:

"The split by field <field> has a large number of unique values <number>. Chart column set will be trimmed to 10. Use globallimit argument to control column count."

- Use very high globallimit in geostats and post process after if needed

- Don't use BY in geostats

- Use lower cardinality BY and/or higher globallimit in geostats

2017-07-13 SPL-143111 "Splunkd daemon is not responding" when edit local windows event log collection
2017-04-04 SPL-140765 Splunk having problems extracting json file consisting of 68k plus key-value pairs
2016-11-29 SPL-133182 When two datasets have identical names but one is local (private) while the other is global, attempts to view or extend the global dataset use results from the local dataset instead.

Federated search issues

Date filed Issue number Description
2024-04-23 SPL-254718, SPL-253248, SPL-255069 Federated searches not completing with error "Socket error during transaction. Socket error: Success"

2024-03-26 SPL-253175, SPL-244551 Federated search failures seen on RSH due to terminated search connections from FSH
2024-03-12 SPL-252488, SPL-248786, SPL-253755 Lookups in transparent mode don't use proper lookup when fsh and rsh have lookup with same name
2024-02-23 SPL-251536 Block edit request to change existing federated provider mode and useFSHKO settings
2024-01-18 SPL-249666, SPL-244551 FS-StandardMode : Standalone sub-search with HEAD doesn't return any results
2023-12-21 SPL-248786, SPL-252486, SPL-252487, SPL-252488 Lookups in transparent mode don't use proper lookup when fsh and rsh have lookup with same name

Workaround:
If the `rsh` is getting transparent searches and it does not have indexers connected to it, the `rsh` does not look on the kvstore values that were sent to it from the `fsh`.

The workaround is to have indexers attached to the `rsh`

2023-09-05 SPL-244248, SPL-239298 Federated Search, Enterprise --> Cloud configuration: Performance degradation increases when the number of indexers increases in the RSH

Workaround:
One possible workaround is to use a more efficient query. For example, use "| tstats count where index=main by splunk_server" instead of "index=main | stats count by splunk_server".


Another workaround is to change the max_workers_searchparser setting to a value lower than its default.

Use this workaround if you are using your Splunk Enterprise federated search head (FSH) instance only for running federated searches. This workaround might affect non-federated searches.

On the Splunk Enterprise FSH, follow these steps:

  1. Create limits.conf in a local/ folder.
  2. Set the max_workers_searchparser setting to a number lower than its default (1 or 2). For more information about this setting see the Admin Manual.
  3. Test which setting value provides a better performance.

2023-07-20 SPL-242282, SPL-242864 Federated Searches fail for union commands when query optimization diverge between FSH x RSH
2023-07-12 SPL-242049, SPL-248189, SPL-248311, SPL-248312 Kvstore files are not converted to csv files in the bundles when local indexers are not present even when remote providers are present

Workaround:
If an indexer ( a distributed peer ) is added to the local deployment ( the federated search head ), then the issue is resolved.

On deployment that don't have indexers at the moment a low performance indexer should be created ( on a vm etc ) and added as a distributed peer.

2023-06-26 SPL-241446 rsh_sid should be logged in the fsh audit log as well
2023-05-22 SPL-240242, SPL-262206 Federated Search: When exporting results, the remote search head (RSH) returns exceptions when it sees federated search head (FSH) socket errors. The RSH should ignore FSH socket errors.
2023-05-02 SPL-239436 In standard mode federated search, outputlookup existence check on RSH causes search to terminate early although it is not run on RSH

Workaround:
Define the lookup on both federated search head and remote search head.
2023-04-17 SPL-238767, SPL-244936, SPL-244937 Standard mode federated search with longer than a minute From command searches, encounters socket ReadWrite error when the federated provider points to a cloud Load balancer, due to idle timeout on the LoadBalancer config

Workaround:
If you encounter this issue, update the federated provider definition (created on the federated search head in Splunk Web), so that its Remote Host points to a remote deployment cluster member instead of to the remote deployment cluster load balancer.
2023-04-14 SPL-238738 Federated Search for Splunk does not support the "Show Source" Field Action
2023-04-11 SPL-238512, SPL-239266 Federated search UI does not support mapping federated indexes to data model datasets that have dot characters in their names
2023-04-10 SPL-238501 Federated search "outputlookup" command cannot add data to local lookup table

Workaround:
Define the same lookup on the remote search head too, so the remote search head will not error out early and return 0 results.
2023-03-30 SPL-238029, SPL-239359, SPL-239360 Standard mode federated search - A multistats search with a tstats subsearch where prestats=t and a federated index is used as a data model throws an error.
2023-03-28 SPL-237883, SPL-239361, SPL-239362 Transparent Mode federated search - Using table and stats in the same federated search causes the search to return empty results , when run in smart or fast mode

Workaround:
Run searches in VerboseMode to ensure all fields are returned to the FSH.
2023-03-24 SPL-237796, SPL-248319 In transparent mode Federated Search for Splunk, the makeresults command returns more rows than expected

Workaround:
Convert all occurrences of makeresults to makeresults | head 1.

If you need more results, change the head command parameter accordingly. For example,makeresults count=5 would become makeresults count=5 | head 5.
2022-12-06 SPL-233685, SPL-214007, PSRT-3936 Federated search: An HTTP parser error causes searches of saved search datasets with long queries to end abruptly
2022-10-31 SPL-232219 Resolve event count issues for Tstats in Standard mode when append=true
2022-10-19 SPL-231712 Create/Edit Role - In the UI, the "Wildcards" tool cannot be used to specify allowed federated indexes for standard mode federated search
2022-09-26 SPL-230682 Tstats returns incorrect event counts when using append=true
2022-08-23 SPL-228969 Federated Search: In Splunk Web federated index UI you cannot provide data model Dataset Name values that contain a dot ( . ) character

Workaround:
This is a limitation for users of standard mode federated search who want to set up federated indexes that map to data model datasets. It means that such users cannot set up federated indexes for data model datasets that are subordinate to a root dataset. For example, if the root data model dataset is Network_Traffic, you cannot map a federated index to the subordinate data model dataset Network_Traffic.All_Traffic.

As a workaround, users can run tstats searches that use the nodename argument to filter out data that does not belong to a specific data model dataset: | tstats ... where nodename=Network_Traffic.All_Traffic.
2022-07-27 SPL-227530, SPL-234988 Splunk-to-Splunk federated search: After upgrade, the remote search head gets stuck in a loop of transferring proxy bundles to the remote indexers and failing

Workaround:
To stop a proxy bundle (pb_t1) from being sent endlessly from the remote deployment to it's indexers, you need to ensure that the local deployment generates a new bundle. Once this one new bundle is generated and sent to the remote deployment (as (pb_t2), the remote deployment will stop sending the previous bundle to the indexers.

To make sure that happens: 1. There must be a valid transparent mode federated provider definition that connects the local deployment to the remote deployment that keeps sending the proxy bundle. 2. You can create a dummy tag on the local deployment to trigger the bundle replication from the local deployment to the remote deployment. 3. Trigger a search from the local deployment. This will make sure that the bundle is sent ASAP towards the remote deployment.

2022-07-15 SPL-226877 Federated Search UI Error: Cannot create saved search dataset for federated index if dataset name contains space

Workaround:
Use REST API to create the federated saved search instead:

curl -k -u <username>:<password> -X POST https://localhost:8089/servicesNS/nobody/search/data/federated/index -d name=federated:index_kathy -d federated.dataset='savedsearch:ss with space' -d federated.provider=remote_deployment_1

See Federated search endpoint descriptions in the REST API Reference Manual.

2022-02-25 SPL-219793 Some commands in federated searches return incorrect resultCount values when run in verbose mode

Workaround:
Use Verbose and Smart mode specifically for searches with transforming commands like stats, chart, and timechart, and then review the results in the Statistics tab. To review event counts, run non-transforming searches in Fast mode.

Search-time field extraction usually requires searches without transforming commands that run in either Verbose or Smart mode. When you run searches in Fast mode, you can ensure that search-time field extraction takes place for federated searches by appending | fields * to the ends of your searches.

Refreshing the browser tab will temporarily resolve the issue. No root cause/fix has been identified yet.

  • Remove any settings that define default values already set in the /default/distsearch.conf file.
  • Removes comments preceded by a hash.
  • Reorders the KV pairs alphanumerically within a stanza.
  • Reorders stanzas within the file.

Workaround:
Splunk recommends customers set `useACK` to true to ensure in-memory is not dropped in the event of indexer rolling restarts or repaving. Thus, the best short-term solution is to set `useACK` to `true`.
2022-08-18 SPL-228672, SPL-231396 validation of bundle returns "restart required" always on any app when there is a password field with encrypted bundles

Workaround:
Make all encrypted fields writable in the metadata/local.meta files inside etc/manager-apps/ (so, where you find "write : [ somerole ]", you might change it to "write : [ * ]" or "write : [ role_that_user_applying_bundle_has ]"
2022-03-28 SPL-221431, SPL-216614 Searchable Rolling Restart stuck reassigning primacy when indexers take more than streaming_replication_wait_secs to roll their buckets when being decommissioned.

Workaround:
Increase server.conf[clustering]streaming_replication_wait_secs to ensure all streaming targets will be completed. streaming_replication_wait_secs=1800 (a maximum wait of 30min) is not unreasonable, but the setting will affect all types of CM-initiated restarts, so make sure not to set it too high.

Workaround:
As a workaround, disable useAck in outputs.conf on the forwarder. After disabling, indexers start to ingest data.

If you need useACK to prevent data loss, disabling autoBatch in outputs.conf can remediate the issue too, but it impacts throughput - no worse than 8.x, but no improvement for 9.0.

Workaround:
Following steps should be followed:

- to reconfigure subscription type to RenderedText:

wecutil ss <subscription-name> /cf:RenderedText

- in order to work around a MS defect on the WindowsEventViewer causing field description resolution failures within the WindowsEventViewer, when configuring RenderedText contentFormat you might want to also change the subscription locale, if not already done, to en-US:

wecutil ss <subscription-name> /l:en-US

and the same also for the datetime format on the WEC server to English (United States), see also here:

https://serverfault.com/questions/606144/win2012r2-eventlog-subscription-dont-display-informations https://social.technet.microsoft.com/Forums/ie/en-US/3fd3d1fc-1194-4899-978c-3283085648bc/eventlog-forwarding-issues-either-the-component-that-raises-this-event-is-not-installed-on-your

- please make sure to install the most recent Windows add-on compatible with your Splunk release, following the official installation documentation:

https://docs.splunk.com/Documentation/AddOns/released/Windows/Install

- please configure inputs.conf on the splunk instance running on the WEC server as follows, in order to onboard the ForwardedEvents data in XML format:

[WinEventLog://ForwardedEvents]
renderXml = true

then save and restart splunk in order to apply the changes.

- last, but not least, unless renderXml was set to true already before installing/upgrading to a regressed version, you will need to rewrite your searches and reports in order to comply with the new/XML-specific field extractions shipped in the Windows add-on, since the data is now onboarded in XML format.

2018-08-13 SPL-158658 A timeout or slow response when accessing Splunk Web Licensing page

Workaround:
A timeout or slow performance of the license management page is caused by a build-up of historical license warning messages, which are processed every time the page is accessed. Can be verified by running this search on the License Manager:

| rest splunk_server=local /services/licenser/messages

If a high value is returned for that end point, you are likely affected. Log a support ticket with Splunk to obtain a license reset key, and apply the key to clear out any historical license warning messages. After the reset license is applied, the license management pages should load normally.

2023-05-02 SPL-240700 A forwarder that does not have a 'clientCert' set in its outputs.conf configuration file will not connect over TLS to a receiver even when the receiver has 'requireClientCert' set to "false" in its inputs.conf configuration file

Workaround:
Specify a value for 'clientCert' in the outputs.conf file on the forwarder. Ensure that the file you specify for the setting exists and is a valid file in Privacy Enhanced Mail (PEM) format.
2023-01-06 SPL-234643 Splunkd abort - due to 3rd party S2S client unable to process ACKs.

2022-10-05 SPL-231139, SPL-228404 Following upgrade to 9.0 customer HF blocks queues when Ingestion latency bug hits

Workaround:
disable what we can from ingestion latency reporter in health.conf on HF:

\[health_reporter] aggregate_ingestion_latency_health = \[0|1]

  • A value of 0 disables the aggregation feature for ingestion latency health reporter.
  • Default: 1 (enabled).

Disable that please. And the feature itself. \[feature:ingestion_latency] alert.disabled = 1

disabled = 1

2022-07-29 SPL-227621, SPL-241402, SPL-227998 Export of search results in the GUI fails with "Service Unavailable" with PYTHONHTTPSVERIFY=1

2022-05-25 SPL-225455 Splunk Assist: On indexer cluster managers, an "Error loading assist: try the operation again or contact Splunk support" message appears
2022-04-12 SPL-222543, SPL-224946 Unable to generate diag - "UnicodeDecodeError: 'utf-8' codec can't decode byte XxXX in position YY: invalid start byte"

Workaround:
The problem is caused by non-ASCII/UTF-8 characters, that are present in your configuration and are not supported. You can remediate the problem:

1. Either remove non-ASCII/UTF-8 characters from your configuration files. 2. Or take a backup of '$SPLUNK_HOME/lib/python3.7/site-packages/splunk/clilib/cli_common.py' and in line 127: Add parameter to "line.decode" - either "errors='replace'", or "errors='ignore'". Eg: line.decode(errors='replace')

2022-04-06 SPL-222105 When all inherited roles are taken out from admin role, it will cause admin user failed to show other users even though all capabilities is set natively.

Workaround:
Two possible approaches:

1. Remove the option grantableRoles = admin from authorize.conf - this is not permanent workaround and will need to be done every time admin role is modified.

2. Add any capabilities that the other user roles have to the "admin" role.

2022-02-24 SPL-219715, SPL-225376, SPL-225374, SPL-225375 Workload Management fails to enable on restart if a rule contains a role that is missing on the platform
2021-04-24 SPL-204740, SPL-204735 Deletion of a workload pool is allowed if there is a 'disabled' rule that is related to that workload pool and this can cause errors if the rule is re-enabled later

Workaround:
To prevent this issue: When you delete a workload pool, please make sure that you delete any disabled workload rules that are associated with that workload pool.

To resolve the issue if you encounter this: Disable or delete the workload rule that is associated with a workload pool that does not exist anymore.

2021-04-20 SPL-204428, SPL-203620 AWS SDK log messages should not be turned on for on-prem builds

2021-03-19 SPL-202682 The license usage report tab name is Previous 60 days, but the reports run over the last 30 days
2021-02-10 SPL-200532 SmartStore: Stuck fixup due to inability to freeze unsearchable/unstable bucket

Workaround:
This issue is caused by a single unsearchable bucket that has been frozen while not existing on remote storage. The bucket copy on the peer node's cache remains stuck in the fixup state, resulting in messages to the effect that all data is not searchable, the replication factor is not met, and the search factor is not met.

To resolve, on the peer node, invoke the "/services/cluster/peer/buckets" endpoint, specifying the faulty bucket, setting "search_state=Searchable" to make the bucket searchable. You do not need to restart the peer node afterwards.

Here is the syntax for the required endpoint:

curl -k -u admin https://<peer_node_with_bucket>:<mgmt_port>/services/cluster/peer/buckets/<bucket_id>/change_bucket -d bucket_mask=0 -d search_state=Searchable -d generation_id=0 -d searchable_sources="peer,site,server_name,host_port_pair,replication_port,replication_use_ssl,searchable,bucket_mask"

Note that pairs of angle brackets indicate variables that must correspond to your instance and bucket.

2020-05-06 SPL-188800 Starting Splunk software with incorrect KV store storage engine causes KV store to crash

Workaround:
In the [kvstore] stanza of your server.conf file, set the storageEngine setting to match the storage engine that you're using, either wiredTiger or mmapv1. To learn which storage engine you're using, check whether the file extensions in the var/lib/splunk/kvstore/mongo directory are *.wt for Wired Tiger or *.ns for Memory Mapped.

Splunk Analytics for Hadoop

Date filed Issue number Description
2017-04-04 ERP-2040 Splunk archiving fails for large block sizes (buckets) due to HDFS write crashes for Hadoop version 2.8, 2.7.x

Workaround:
Upgrade Hadoop to 2.8.2 or higher.
2015-09-09 ERP-1650 timestamp data type not properly deserialized.
2015-08-05 ERP-1619 Searching on a newly created archive index before the bucket copy saved search is run causes a filenotfound exception.

Workaround:
Reenable the bucket copy saved search and let it run, or force the archiving to happen via | archivebuckets force=1 and then rerun the search.
2015-07-07 ERP-1598 minsplit rampup - splits generation takes too long.

Workaround:
Set minsplits=maxsplits
2015-05-12 ERP-1502 Non-accelerated pivot search on Pivot UI page waits for a long time to return result.
2015-01-08 ERP-1343, SPL-95174 Splunk Analytics for Hadoop searches fail on corrupted journal.gz files, although Splunk searches run without error.

Add the journal.gz to the input path's blacklist (vix.input.1.ignore = ....)
2014-10-27 ERP-1216 Data Explorer preview does not honor existing sourcetypes for big5/sjis files.
2014-10-03 ERP-1164 Report acceleration summary gets deleted when two Splunk Analytics for Hadoop instances point to the same Splunk working directory.

Workaround:
To mitigate this issue, make sure that vix.splunk.home.hdfs (or Working directory in the UI) is unique on both search heads that are not in a pool. To keep your instances in the same working directory, configure vix.splunk.search.cache.path to be unique on both search heads.
