Upgrade issues

Date filed Issue number Description
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>


Authentication and authorization issues

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

Workaround:
Turn off PYTHONHTTPSVERIFY for now

https://docs.splunk.com/Documentation/Splunk/latest/Security/EnableTLSCertHostnameValidation#Configure_TLS_host_name_validation_for_Splunk_Python_modules

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.

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]
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>


2016-07-26 SPL-125052 Sole Admin can demote themself to Power without path of recovery in GUI.

Workaround:
Through the command line, you can open notepad and modify the password file to regain 'Admin' status.

Data input issues

Date filed Issue number Description
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
2022-04-08 SPL-222366 Ingest Actions does not work with Splunk Free, Personalized Devtest, Developer, and Forwarder-only licenses

Search issues

Date filed Issue number Description
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.

2023-06-09 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
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

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.
2014-10-02 SPL-91638, SPL-107375 For scheduled searches in a search head cluster, empty search jobs may appear in the job inspector for a cluster member.

Federated search issues

Date filed Issue number Description
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
2023-05-22 SPL-240242 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.
2023-04-14 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 [[Documentation:SplunkCloud:latest:RESTREF:RESTfederated|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-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.

2022-02-08 SPL-218841 Reporting command in verbose mode returns 0 events despite correct event_count
2021-10-14 SPL-213745, SPL-251131 Standard mode federated search: Unable to set federated index as default index

Saved search, alerting, scheduling, and job management 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.

2019-09-20 SPL-176812 Multiple SH Clustering with single deployer can't use datamodel summary sharing
2018-09-19 SPL-160286 The data preview for the Add Data workflow does not display for Log to Metrics source types
2017-11-29 SPL-146802 Distributed environment requires index defined on search head for log event alerts
2017-08-14 SPL-143947 Report acceleration is broken for users with a configured role-based access filter

Charting, reporting, and visualization issues

Date filed Issue number Description
2024-01-05 SPL-249095, SPL-247587 After upgrading to 9.1.1 dashboards iframe panels load to a blank page
2023-06-30 SPL-241687, SCP-62360 In Dashboard Studio table visualizations, the number 0 is on the left side of cells, but all other numbers are on the right side.
2023-06-29 SPL-241626 Chain searches connected to a base search with a risky command don't provide a pop-up to accept the risky command.

Workaround:
Create another visualization, such as a rectangle, and connect it with only the base search. Accept the risky command activated by the base search.
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.
2023-06-14 SPL-240965 Dashboard Studio home dashboard flickers on specific viewport resolutions with scrollbar visibility set to always

Workaround:
Resize the viewport or current monitor resolution. If the issue persists, try changing the dimensions of the dashboard.
2023-06-08 SPL-240750 Inconsistency in displayed timezone in Dashboard Studio when using time range tokens
2016-04-27 SPL-118911 In SHC, referenced saved real-time searches in a dashboard do not stream results.

Workaround:
See Troubleshoot referenced real-time searches for workaround details.


Distributed search and search head clustering issues

Date filed Issue number Description
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
2021-03-26 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.


2017-11-29 SPL-146802 Distributed environment requires index defined on search head for log event alerts
2017-03-13 SPL-138654 Splunk searches fail when filepath gets too long on Windows
2016-07-12 SPL-124085 On Search Head Cluster It is not possible to remove an App from the SHs once it has been disabled.

Data model and pivot issues

Indexer and indexer clustering issues

Date filed Issue number Description
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
2023-12-19 SPL-248587 Unable to install or upgrade to Splunk Universal Forwarder version 9.1.3

Workaround:

2022-06-06 SPL-225379 Ownership of files mentioned in manifest file is splunk:splunk instead of root:root after enabling boot start as root user for initd

Workaround:
When changing UF user, manually chown SPLUNK_HOME to the new user, including first time install/upgrade, or manually enable boot-start.
2022-03-23 SPL-221239 System Introspect App fails when universal forwarder is installed at non-admin user

Splunk Web and interface issues

Date filed Issue number Description
2023-08-08 SPL-242943, SPL-242699, SPL-246958, SPL-246959 Unable to load app list after upgrading to 9.1 using the Free license
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:

2016-11-23 SPL-132925 Table data rows generated with the addcoltotals command do not show up in PDF

Workaround:
If you are using addcoltotals to generate a totals data row, renaming the _time field can cause PDF generation issues.

Remove the label and labelfield or change the label to a number to generate the PDF as expected.

Admin and CLI issues

Date filed Issue number Description
2023-04-03 SPL-238114 messages.conf roles attribute not working as documented in messages.conf.spec
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.

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.

| rest /services/search/jobs/1668102339.174_23558BC9-6A39-4F4A-9FD2-968C358489B7 splunk_server=local

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.

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.

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.
