Highlighted issues

Date filed Issue number Description
2024-02-05 SPL-250501 Config validation check mistakenly blocks config push on Splunk Enterprise. This issue affects Splunk Enterprise 9.2.0 and is fixed in Splunk Enterprise 9.2.0.1.

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

2024-02-20 SPL-251301 Unable to install/upgrade Splunk Enterprise & UF RPM package v9.2.x on the same server.
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

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

Search issues

Date filed Issue number Description
2024-09-06 SPL-262305, SPL-253147 Crashing thread: TcpOutEloop

Workaround:
https://community.splunk.com/t5/Knowledge-Management/Splunk-crash-during-tcpout-outputs-conf-reload/td-p/699397
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

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.

2023-06-09 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.

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
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

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`

2023-10-31 SPL-246556, SPL-249728, SPL-249746 Federated searches that contain stats count by a field that doesn't exist return 0 events when run in verbose mode
2023-09-20 SPL-244927, SPL-244124, SPL-247063, SPL-246460, PSRT-7170 Federated searches that include 'table' or 'rex' commands return 0 events when run in verbose mode
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
2023-05-02 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.
2023-04-14 SPL-238738 Federated Search for Splunk does not support the "Show Source" Field Action
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.
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

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.

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.

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>

Workaround:
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.

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:
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

Distributed deployment, forwarder, deployment server issues

Date filed Issue number Description
2024-03-18 SPL-252818, SPL-253411, SPL-254631 Deployment Server not displaying Apps correctly after 9.2.0.1 update

Workaround:
Deployment Clients are showing apps as not having been deployed and Server Classes do not show their matching clients. This is just a display issue, the DS will continue to honor the server class filters when deploying the apps.

As a workaround, use the server class's preview function to list the deployment clients. Alternatively, do not use machine type to filter your deployment clients.

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

2021-03-26 SPL-203060 The splunkd process changes the local distsearch.conf on service start

Workaround:
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.

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
