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 [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`.
2023-01-26	SPL-235416	Case sensitive sourcetypes in Ingest Actions UI preview won't fetch results
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
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.
2023-06-28	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
2023-03-28	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.
2023-03-13	SPL-237204, SPL-235493	iplocation command using improper mmdb file after upgrade from 8.1.1 to 9.0.2 Workaround: Use third party lookup GeoLite2-City.mmdb downloaded externally instead of the default file that comes with Splunk.
2022-12-08	SPL-233842, SPL-231946	|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
2022-10-12	SPL-231441, SPL-223053	eventstats will generate less results when time range is large
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.
2022-06-23	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
2022-05-25	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
2021-02-25	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.
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: Create limits.conf in a local/ folder. 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. 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
2023-06-27	SPL-241502, SPL-243208, SPL-243209	Transparent federated search with service account making api calls takes excessive time
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.
2023-04-11	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.
2022-10-19	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.
2022-06-23	SPL-226038	In a transparent mode federated tstats search of an accelerated data model that is located only on the FSH, results are returned only from the FSH, not the RSH, when summariesonly=t
2022-06-16	SPL-225826	Transparent mode federated searches over accelerated data model datasets cannot return remote results because their summaries are not present on the RSH
2022-05-31	SPL-225037	Remote dataset dropdown menu resets to "Index" after selecting federated provider
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
2022-03-09	SPL-220289, SPL-245017	Federated Search Transparent Mode: Commands that have subsearches like join and append may result in failures on RSH due to missing application context Workaround: If the search is being run in an application context that does not exist on the remote deployment, install the missing application on the remote deployment.
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.
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

After upgrade, you can manually fix individual dashboards by opening the source view for an affected dashboard and replace any <set ... /> elements with <set ... ></set>. After upgrade, you can also make a small change in the UI (such as adding a space to your title or description) and click save to reformat the empty tags.
2022-08-17	SPL-228658, SPL-236371, SCP-57718	"Down Arrow" for chart legend scrolling does not work Workaround: Lengthen the chart so the legend is not paginated, or convert the chart to Dashboard Studio, where the legend pagination is not currently an issue.
2022-04-26	SPL-223193, SPL-233133	"Open in Search" function doesn't work with chained searches in Dashboard Studio when the time range depends on an input/token, showing error "Invalid earliest_time"
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.

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.
