Upgrade issues

Date filed Issue number Description
2024-04-04 SPL-253690, SPL-247255 Issue with Splunk Enterprise version 9.1.x and 9.2.0 when connected to proxy server

Workaround:
An enhancement was introduced to the search process in Splunk Enterprise version 9.1.1 that optimizes searches by using the peer's IP address instead of querying DNS for the target peers. If an http_proxy is specified in the server.conf file, the enhancement causes the originating peer's IP address to fail to resolve. As a result, the IP address of the proxy, instead of the originating peer, is logged and utilized in the peers.csv file during search operations, causing the following error message to display in Splunk Web: "Received error from proxy server".


To disable the new DNS query optimization and eliminate the error, add the following setting to the distsearch.conf file:


[distributedSearch]
useIPAddrAsHost=false

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.

2020-08-31 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

[user_info]
PASSWORD = <yourpassword>


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`.
2022-08-17 SPL-228646, SPL-228645 Restart is needed when AWS access key pairs rotate (w/o grace period) or other S3 config settings for Ingest Actions become invalid
2022-08-09 SPL-228117, SPL-257140 "file" is incorrectly listed as a supported scheme for ingest actions in outputs.conf.spec
2022-04-08 SPL-222366 Ingest Actions does not work with Splunk Free, Personalized Devtest, Developer, and Forwarder-only licenses

Search issues

Date filed Issue number Description
2024-05-09 SPL-255514 "| timechart count" search is causing Splunk to crash with "Crashing thread: searchOrchestrator"

Workaround:
When using a search with only the timechart command in a search:

| timechart count

Splunk instance will crash with "Crashing thread: searchOrchestrator". Currently there is no workaround other than not using this search string

2024-04-12 SPL-254077, SPL-241370 CIDR match for tstats with ipv6 addresses isn't supported

Workaround:
The tstats command currently doesn't filter events with CIDR match on fields that contain IPv6 addresses. Running tstats searches containing IPv6 addresses might result in the following error indicating that the addresses are treated as non-exact queries:
Error in 'TsidxStats': WHERE clause is not an exact query

2024-04-04 SPL-253690, SPL-247255 Issue with Splunk Enterprise version 9.1.x and 9.2.0 when connected to proxy server

Workaround:
An enhancement was introduced to the search process in Splunk Enterprise version 9.1.1 that optimizes searches by using the peer's IP address instead of querying DNS for the target peers. If an http_proxy is specified in the server.conf file, the enhancement causes the originating peer's IP address to fail to resolve. As a result, the IP address of the proxy, instead of the originating peer, is logged and utilized in the peers.csv file during search operations, causing the following error message to display in Splunk Web: "Received error from proxy server".


To disable the new DNS query optimization and eliminate the error, add the following setting to the distsearch.conf file:


[distributedSearch]
useIPAddrAsHost=false

2024-03-28 SPL-253286 The limits.conf.spec file doesn't include the updated description for the 'read_final_results_from_timeliner' setting

Workaround:
The description for the 'read_final_results_from_timeliner' setting was not updated in the limits.conf.spec file for Splunk Enterprise 9.1.1. The description for the setting should note that the setting value shouldn't be set to "1" to indicate "true", as follows:

read_final_results_from_timeliner = <boolean>

  • When you run a search of event data where 'status_buckets > 0', this setting controls the contents of the results.csv.gz and results.srs.zstd files in the search artifact.
  • When set to "true", the final results saved to disk by the search process on the search head are a sample of events ready from the timeliner. Do not set the value to "1" to indicate "true", because some systems might not parse this value correctly.
2023-12-18 SPL-248552 ProcessDispatchedSearch error displayed - The process cannot access the file because it is being used by another process

Workaround:
There is no workaround.

Details
This issue affects Microsoft Windows environments only.

The only impact of this error is that some log lines might be dropped from Splunk's own search.log and splunkd.log files. Searches still work as usual.

2023-12-12 SPL-248297 Higher memory usage than usual on Windows systems after upgrade from Splunk Enterprise version 9.0/8.x to version 9.1.x/9.2.x

Workaround:
As of Splunk Enterprise version 9.1.x, a new system call for allocating memory called mimalloc has been implemented on Windows. Prior to Splunk Enterprise version 9.1, the Splunk Enterprise implementation for Windows used a default system call. The new mimalloc system call can cause an increase in memory usage, which impacts search heads, indexers, and universal forwarders, especially when data model acceleration is in use. This issue will be fixed in Splunk Enterprise versions 9.1.5 and 9.2.2.

Upgrade to Splunk Enterprise version 9.1.5 or 9.2.2 when they become available.

2023-10-27 SPL-246383, SPL-246534, SPL-246535, SPL-246536, SPL-246537, SPL-246538, SPL-246539 Excessive logging in AuditLogger of "action=admin_all_objects, info=denied" after upgrade from 9.0.4 to 9.1.1
2023-10-03 SPL-245287, SPL-245166 UTF-8 characters should not be hex-encoded in Splunk logs.

Workaround:
1. Identify the specific log files that are improperly escaping UTF-8 characters.

2. For each log file, find the appender name corresponding to the log file in $SPLUNK_HOME/etc/log.cfg. For example, the splunkd.log log file is defined by this appender:
appender.A1.fileName=${SPLUNK_HOME}/var/log/splunk/splunkd.log

3. Add a new line in $SPLUNK_HOME/etc/log.cfg as follows corresponding to the appender name:
appender.<appender name>.escape=false
For example, for the A1 appender which governs splunkd.log, add the line: appender.A1.escape=false

4. Restart Splunk.

2023-09-25 SPL-245065, 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.

2023-09-19 SPL-244841, SPL-244119 Search processes segfault'ing due to Logger appender without layout definition
2023-06-09 SPL-240774 The DELIMS setting or the kvdelim option may not be applied correctly when the k/v delim character appears 2 or more times in a field value

Workaround:
Perform field extractions by modifying your searches using other commands, such as the rex command or eval command.
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.

2023-03-15 SPL-237347 Splunk Enterprise + 9.0.4 + Job inspector incorrectly shows "This search has completed, but did not return any results."

Workaround:
Use true <or> false to enable/disable flags in configuration files rather than 0 <or> 1
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.
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
2021-02-25 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.
2020-12-04 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

Federated search issues

Date filed Issue number Description
2024-10-15 SPL-264529, SPL-261801 Search with mcatalog command returns missing metrics when used with append=t and last index is not valid
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.

2023-08-28 SPL-243968, SPL-239689, SPL-244367 In transparent mode Federated Search for Splunk, custom search commands and the "outputlookup" command should run only on the local deployment. Instead they run on the remote deployment, leading to errors, incorrect results.
2023-08-14 SPL-243209, SPL-241502 Transparent federated search with service account making api calls takes excessive time
2023-07-20 SPL-242282, SPL-242864 Federated Searches fail for union commands when query optimization diverge between FSH x RSH
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.
2023-03-24 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.
2022-10-19 SPL-231712 Create/Edit Role - In the UI, the "Wildcards" tool cannot be used to specify allowed federated indexes for standard mode federated search
2022-07-15 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.

2022-05-31 SPL-225037 Remote dataset dropdown menu resets to "Index" after selecting federated provider
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.

2022-02-08 SPL-218842, SPL-252272, SPL-242740 Some reporting commands in federated search return incorrect eventCount

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.

Saved search, alerting, scheduling, and job management issues

Date filed Issue number Description
2024-01-19 SPL-249712 Emails from alerts not sent when using sendemail due to authentication error caused by changes in cli_common library

Workaround:
Replace Python scripts for sendemail with older versions, specifically sendemail.py and sendemailhandler.py. The Python scripts are located in the Search and Reporting app under $SPLUNK_HOME/etc/apps/search/bin.
  1. Run a test search to confirm emails are NOT arriving.
  2. Confirm/update email settings in one UI (email config, ensure linkhostname is blank, ensure there is no reply email is in the field "send as").
  3. Allow time for replication.
  4. Confirm email settings in UI on each box (email config, ensure linkhostname is blank, ensure there is no reply email is in the field "send as").
  5. Backup 9.1.x sendemail Python scripts on each host.
  6. Remove 9.1.x sendemail Python scripts on each host.
  7. Restore 9.0.x backup sendemail Python scripts on each host.
  8. Run a test search to confirm emails are arriving on each host.

2023-07-21 SPL-242301, SPL-231558 The UI trigger for summary rebuild doesn't work for some accelerated data models that have no root-event dataset and have a reporting command in first root search dataset

Workaround:
The workaround is to change the Data Model definition to reorder the root search objects such that the root search object that can be accelerated is the very first one in the list.

For instance, for the provided `test_internal_audit_logs.json`, edit the JSON file on disk and move `failed_searches` dataset before `fully_completed_searches`.

2023-07-07 SPL-241821 Data Model Accelerations that have Automatic Rebuilds enabled may lead to unbounded memory growth due to search expansion, resulting in Out of Memory errors

Workaround:
For a data model that is experiencing high memory usage, perform the following steps:
  1. On your Splunk platform deployment, in Splunk Web, select Settings and then Data Models.
  2. Select Edit for the data model that is experiencing high memory usage, and then select Edit Acceleration.
  3. Open Advanced Settings.
  4. Disable Automatic Rebuilds.

Furthermore, applying index constraints to restrict the list of indexes searched for building a given DMA summary and applying tags allowlisting would help curtail the memory usage.

Workaround:
If possible, hard code the img src domain and capture the rest of the img URL as a token. For example, instead of `<img src="$image_url$">`, use `<img src="https://www.example.com/$image_url$">` and remove the domain from the value of $image_url$.

Another option is to add a hidden placeholder image to the HTML panel with the issue: <style>

2023-06-21 SPL-241274 Dashboard Studio fails to load dashboards and displays the error "Cannot convert undefined or null to object" when search results return "null" values.

Workaround:
Replace the "null" value with "empty" by appending an SPL replace command to the search query. For example, | replace "null" WITH "empty" IN <fieldname>.
2023-06-14 SPL-240964 Visualization action buttons are not working as expected in Dashboard Studio home dashboards.

Workaround:
Open the impacted dashboard in its original dashboard page instead of the home dashboard page.

There is no workaround. After upgrading to Splunk Enterprise 8.x, the splunkd process checks and modifies the local/distsearch.conf on each service start. The process will:
  • 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.

Data model and pivot issues

Date filed Issue number Description
2023-07-21 SPL-242301, SPL-231558 The UI trigger for summary rebuild doesn't work for some accelerated data models that have no root-event dataset and have a reporting command in first root search dataset

Workaround:
The workaround is to change the Data Model definition to reorder the root search objects such that the root search object that can be accelerated is the very first one in the list.

For instance, for the provided `test_internal_audit_logs.json`, edit the JSON file on disk and move `failed_searches` dataset before `fully_completed_searches`.

2023-07-07 SPL-241821 Data Model Accelerations that have Automatic Rebuilds enabled may lead to unbounded memory growth due to search expansion, resulting in Out of Memory errors

Workaround:
For a data model that is experiencing high memory usage, perform the following steps:
  1. On your Splunk platform deployment, in Splunk Web, select Settings and then Data Models.
  2. Select Edit for the data model that is experiencing high memory usage, and then select Edit Acceleration.
  3. Open Advanced Settings.
  4. Disable Automatic Rebuilds.

Furthermore, applying index constraints to restrict the list of indexes searched for building a given DMA summary and applying tags allowlisting would help curtail the memory usage.

Indexer and indexer clustering issues

Date filed Issue number Description
2024-05-29 SPL-256657, SPL-255517 Indexer Discovery deadlock during tcpout reload
2024-04-04 SPL-253649, SPL-246435 Rolling Restart generate fix-up task that search factor taking hours complete as search files replication fails.

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`.
2016-08-25 SPL-127353 Data rebalance finishes early when one peer is the source for all buckets

Workaround:
when only one indexer in a cluster indexed data (has all the searchable copies), rebalance once before adding the new indexer, and then rebalance a second time

Universal forwarder issues

Date filed Issue number Description
2023-12-14 SPL-248479, SPL-253092 9.1.1 HF enters state of constant blocking due to broken S2S protocol

Workaround:
To fix the issue, customers will have to add queueSize on the Splunk HF/IHF instance where persistent queue is enabled, in inputs.conf under the same stanza where persistentQueueSize is set.

inputs.conf [<input stanza>] persistentQueueSize=<no change. keep existing value> queueSize=<100MB or 1% of total system memory(whichever is less)>

2022-03-23 SPL-221239 System Introspect App fails when universal forwarder is installed at non-admin user
2017-03-14 SPL-138731 New 6.6 and later default SHA256/2048-bit key certificates are not compatible with previous versions SHA1/1024-bit key certificates if cert verification is enabled

Workaround:
Users can do any of the following:

1. Disable certificate verification - the same root certificate is available with every Splunk download so enabling certificate verification while using the default certificates provides very little additional security.

2. Generate new SHA256/2048-bit key certificates using the new 6.6 root certificate and distribute to older versions of Splunk

3. Generate SHA1/1024-bit key certificates using the old root certificate to use with your new 6.6 instance. For convenience, the old root certificate is included in 6.6 in $SPLUNK_HOME/etc/auth/prev_release/

2023-03-15 SPL-237347 Splunk Enterprise + 9.0.4 + Job inspector incorrectly shows "This search has completed, but did not return any results."

Workaround:
Use true <or> false to enable/disable flags in configuration files rather than 0 <or> 1
2022-05-31 SPL-225037 Remote dataset dropdown menu resets to "Index" after selecting federated provider
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

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.

2017-11-29 SPL-146820 Unable to access some settings/manager pages (data model editor) if starting from the setup page of a non-visible app

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.

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.

2021-03-19 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.

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.

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.
