Date filed Issue number Description
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>


2017-05-23 SPL-141964 Older 6.0 and 6.1 maintenance release forwarders unable to forward events to 6.6.x and later indexers via splunktcp-ssl.

Workaround:
This affects communication between Splunk 6.6.x and later indexers and:
  • 6.0.0 to 6.0.6 forwarders
  • 6.1.0 to 6.1.4 forwarders

Upgrade your older forwarders to the latest maintenance releases or on your 6.6.x Indexer, add to inputs.conf:

[SSL]
sslVersions = *,-ssl2
cipherSuite = ALL:!aNULL:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM


2017-05-23 SPL-141961 Older 6.0, 6.1, 6.2, 6.3 maintenance release versions unable to connect to 6.6.x and later via management port

Workaround:
This applies to License Master/Slave, Deployment Server/Client, Cluster Master/Peers, Search Head/Peers and affects Splunk 6.6.x and the following versions:
  • 6.0.0 to 6.0.6
  • 6.1.0 to 6.1.4
  • 6.2.0 to 6.2.6
  • 6.3.0 to 6.3.1
  • 6.3.1511.1

Upgrade your older instances to the latest maintenance releases or on your 6.6.x Splunk instances. Add the following stanza to server.conf:

[sslConfig]
sslVersions = *,-ssl2
sslVersionsForClient = *,-ssl2
cipherSuite = TLSv1+HIGH:TLSv1.2+HIGH:@STRENGTH


2017-03-20 SPL-139019 Possible compatibility issues between Python / SDK clients and new 6.6 and later default sslVersions, cipherSuites

Workaround:
Users can do either of the following:

1. Overwrite the new Splunk 6.6 server.conf [sslConfig] sslVersions, cipherSuites with your own settings that are compatible with your version of OpenSSL, e.g. the previous defaults from 6.5.x are compatible with OpenSSL 0.9.8 on Mac OSX:

[sslConfig]
sslVersions = *,-ssl2
sslVersionsForClient = *,-ssl2
cipherSuite = TLSv1+HIGH:TLSv1.2+HIGH:@STRENGTH

2. For some more up-to-date clients, it is possible to enforce TLS1.2 (e.g. --tlsv1.2 for curl) in order to connect successfully.

3. Upgrade OpenSSL on your platform and link it with your client (e.g. Python, curl, etc..). For example, OpenSSL 1.0.2 is currently available on Mac OSX via Homebrew (see https://brew.sh) and is compatible with the new Splunk 6.6 default sslVersions, cipherSuites.

2017-03-13 SPL-138647 Possible compatibility issues between new 6.6 and later default sslVersions, cipherSuites and external services, e.g. e-mail, LDAP

Workaround:
If security is not a significant concern, simply revert back to the 6.5.x SSL/TLS defaults, e.g. for e-mail, add to $SPLUNK_HOME/etc/system/local/alert_actions.conf

[email]
sslVersions = *,-ssl2
cipherSuite = TLSv1+HIGH:TLSv1.2+HIGH:@STRENGTH


for LDAP, add to $SPLUNK_HOME/etc/openldap/ldap.conf

TLS_PROTOCOL_MIN 3.1
TLS_CIPHER_SUITE TLSv1+HIGH:TLSv1.2+HIGH:@STRENGTH


If you would like to retain the more secure 6.6.x defaults, but prefer to add an exception for your less secure external services, follow the procedure below:

1. To determine what sslVersions and cipherSuites are supported by a server, run splunk cmd openssl s_client -connect hostname:port | awk '/Protocol/ || /Cipher/ || /Verify/'.

The example below is for a Postfix SMTP server:

eserv@indexer01:~$ splunk cmd openssl s_client -connect smtp-server01:465 | awk '/Protocol/ || /Cipher/ || /Verify/'
depth=1 C = US, O = Example Customer, OU = IT, CN = Example Customer IT CA, emailAddress = customer@example.org verify error:num=19:self signed certificate in certificate chain New, TLSv1/SSLv3, Cipher is DHE-RSA-AES256-SHA

   Protocol : TLSv1 
   Cipher : DHE-RSA-AES256-SHA 
   Verify return code: 19 (self signed certificate in certificate chain)

2. Check the OpenSSL output for Protocol and Cipher. In the example above, Protocol = TLSv1 and Cipher = DHE-RSA-AES256-SHA

3. Update Splunk's relevant sslVersions and/or cipherSuite. In the example above, sslVersions should be set to tls (allows TLSv1, TLSv1.1, TLSv1.2) and DHE-RSA-AES256-SHA should be appended to the end of the default cipherSuites definition, e.g. add $SPLUNK_HOME/etc/system/local/alert_actions.conf:

[email]
sslVersions = tls

cipherSuites = ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA

2014-08-20 SPL-89640 When running Splunk on Linux as non-root user and using RPM to upgrade, the RPM writes $SPLUNK_HOME/var/log/introspection as root, causing errors upon restarts

Workaround:
Chown the $SPLUNK_HOME/var/log/introspection directory to the user Splunk Enterprise runs as after upgrading and before restarting Splunk Enterprise.
2013-08-19 SPL-73386 Users are not allowed to run historical scheduled search

Workaround:
1. Create a special power/admin user who can run scheduled searches.

2. Assign this user ownership of the scheduled searches.

3. Share the searches at the app level and grant read/write permission to the correct set of users.

Data input issues

Date filed Issue number Description
2017-08-17 SPL-144130 After data input and click 'start searching' will redirect to Launcher app
2017-07-19 SPL-143236 Custom sourcetype is not displayed on sourcetype menu

Workaround:
Set a filter and the sourcetype will display.
2015-11-12 SPL-109362 When the disk runs out of space for the limit set in the server.conf, add data workflow gets stuck with "Uploading file" message modal in the review stage
2015-05-22 SPL-101981 Field extractions do not work when sourcetypes use quotes in the Getting Data In interface.
2015-03-17 SPL-98163 INDEXED_EXTRACTIONS=W3C is truncating field cs_uri_stem when spaces are present in URL

Workaround:
Create a separate extraction in props.conf where defined w3c extraction method:

EXTRACT-cs_uri_stem1 = (GET|POST) (?<cs_uri_stem1>[^-]++)

2014-03-10 SPL-81637 Splunkd preview runs indefinitely on any file preview with "DATETIME_CONFIG=none".
2013-10-29 SPL-75764 Forwarder forwards duplicate data after props.conf is in place for cross platform scenario/when the forwarder is on Solaris and the indexer is on Linux.
2013-10-11 SPL-75116 The UI does not show configured items of some newly converted windows modular inputs that contain the name "default" in the stanza

Workaround:
Edit inputs.conf: in stanzas that contain WinRegMon://default, replace "default" with something else, then restart splunk.
2013-09-10 SPL-74209, SPL-74167 Persistent queues are not created on Windows for stanzas that contain unusual characters (such as < and >).

Workaround:
Specify the persistentQueue explicitly in the input definition.

Search issues

Date filed Issue number Description
2019-04-05 SPL-168826, SPL-169613, SPL-169614, SPL-169071, SPL-169615 Splunk crashes when auto lookup and default search index are used
2019-02-05 SPL-166001 16MB+ events are not displayed on the search results, but they will be listed on the fields sidebar and in the timeline. search.log message: "SRSSerializer - max str len exceeded - probably corrupt"

Workaround:
Make sure fields are under 16777216 characters (or 16MB, usually _raw is the biggest)

OR

Revert back to the old serialization format (CSV), however, this applies to all searches, so you won't be getting the (performance) benefits of the new format.

$SPLUNK_HOME/etc/system/local/limits.conf: [search] results_serial_format=csv

2019-01-10 SPL-164718, SPL-165363, SPL-166562 limits.conf "phased_execution_mode = singlethreaded" causes issue with field ordering, for example _time showing in legend for a | timechart

Workaround:
Set the value of "phased_execution_mode" to "multithreaded" to restore the correct field order.
2018-12-18 SPL-164107, SPL-169524 the mstats rate(x) function does not work with wildcards in the enhanced syntax

Workaround:
The rate(x) function is designed to be applied to a single counter metric. Use an explicit projection field name or use "_value" syntax with wildcard and group by.
2018-12-13 SPL-163932, SPL-164894 Disabling case_sensitive_match in transforms.conf not working for WILDCARD type lookups

Workaround:
You can normalise the data in the lookup (| eval field=lower(field)) before populating, and doing the same before looking it up.

If you need the denormalised version, you can create a different field for the lookup instead to still have access to the original.

Create lookup: ... | eval field=lower(field) | outputlookup

Use lookup: ... | eval matchfield=lower(field) | lookup <lookup> matchfield ...

2018-11-29 SPL-163319, ITSI-3045, SPL-163454 forceCsvResults parameter is improperly added to summary indexed data

Workaround:
add below to $SPLUNK_HOME/etc/system/local/alert_actions.conf:

[summary_index] command = summaryindex spool=t uselb=t addtime=t index="$action.summary_index._name{required=yes}$" file="$name_hash$_$#random$.stash_new" name="$name$" marker="$action.summary_index*{format=$KEY=\\\"$VAL\\\", key_regex="action.summary_index.(?!(?:command|inline|forceCsvResults|maxresults|maxtime|ttl|track_alert|(?:_.*))$)(.*)"}$"

2018-11-07 SPL-162655, SPL-164505 Add ASNEW keyword to FIELDALIAS to support non-overriding version of aliasing

Workaround:
Avoid applying the same alias field name to multiple original field names.

If you must do this, set it up as a calculated field (an EVAL-* statement) that uses the 'coalesce' function to create a new field that takes the value of one or more existing fields. This method lets you be explicit about ordering of input field values in the case of NULL fields. For example: EVAL-ip = coalesce(clientip,ipaddress)

2018-07-24 SPL-157799, SPL-157619, ITSI-1332 When you click in a generated search to run the search in a separate tab, no results are displayed and no errors are logged because the search process has crashed.
2018-06-15 SPL-155648, SPL-169611, SPL-169612 New phased_execution_mode is spawning extra processes for custom search commands

Workaround:
If the custom search needs to run only once, disable the multithread for all searches.

$SPLUNK/etc/system/local stopped the issue from occurring. [search] phased_execution_mode = auto

Apply this workaround especially for deployment using ITSI, as the bug causes double backfill of the ITSI Episodes.

Beware, the workaround will cause a separate search issue SPL-165363, for splunk versions 7.0, 7.1 and 7.2 until the fix in 7.2.4

2017-08-03 SPL-143607 Searches ordered like this returns false results: search ... | eventstats ... | streamstats ..., because it's being run in batch mode when it shouldn't

Workaround:
Place the delta command before eventstats in the search pipeline:

| delta _time as d | eventstats count

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
2017-03-21 SPL-140175 Aborted delete searches may result in stale lock files being left behind

Workaround:

2015-08-10 SPL-105061, SOLNESS-7274 Broken module prevents splunkweb from starting
2015-06-17 SPL-103247 Filtering on _time uses different semantics for the "=" operator on microseconds depending on whether the value is quoted.
2015-04-23 SPL-100170 Automatic Lookups limitation: No results returned in Smart Mode when there are nested lookups and the intermediate field is not mentioned in the search.
2014-12-22 SPL-94910 The replace function does not apply to fields names with an underscore in them.

Workaround:
Rename the fields before the replace.

... | rename *_* AS *-* | replace "something" by "somethingelse"

2014-11-13 SPL-93039 The relevancy search command does not work, always returning 0 or -inf.
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.
2014-09-15 SPL-90861, SPL-90396, SPL-90886 If search encounters invalid offsets or invalid rawdata at TSIDX offsets, it skips reading any number of events from that bucket. No message is displayed, though the information is added to search.log.

2014-03-15 SPL-81934 For clusters, may be unable to open search results output file for search results in a cluster.

Workaround:
Write to a temp file and rename to the target file.
2014-02-21 SPL-80942 Flashtimeline: 500 Internal Server Error when pasting long URL into panel name.
2013-12-18 SPL-78179 REST /saved/searches App names with special characters have invalid links.
2013-08-19 SPL-73386 Users are not allowed to run historical scheduled search

Workaround:
1. Create a special power/admin user who can run scheduled searches.

2. Assign this user ownership of the scheduled searches.

3. Share the searches at the app level and grant read/write permission to the correct set of users.

Saved search, alerting, scheduling, and job management issues

Workaround:
The workaround is to fix invalid FIELDALIAS definitions in props.conf.

To identify affected field aliases - search through splunkd.log (timeframe prior to the upgrade) or search.log for below warnings:

"WARN FieldAliaser - Invalid field alias specification in stanza"

Each unique invalid FIELDALIAS should be fixed or removed.

2019-03-13 SPL-167708 Apply cluster bundle does not apply bundle to any indexers which are in progress of adding to cluster

Workaround:
restart affected indexer(s)
2018-03-15 SPL-152168 Batch-mode retry can return more or less events than it should due to reordering from thread pool processing.

Workaround:
Before you initiate searchable rolling restart or rolling upgrade, make sure the search_retry attribute in the [search] stanza of limits.conf is set to false (the default).


If you have scheduled searches that must complete, either increase the value of decommission_search_jobs_wait_secs (default=180s) in server.conf, or do not run searchable rolling restart or rolling upgrade during the search's timeframe.

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

2015-02-26 SPL-97385 $SPLUNK_HOME/var/run/splunk/snapshot contains large tarballs in the presence of large ES lookup table files.

Workaround:
The allowable size of the download can be increased by setting the following in server.conf.

[httpServer] max_content_length = 1500MB

The other option is to disable the search which controls the generation of the large lookup file. In this case, the search is:

[Endpoint - Local Processes Tracker - Lookup Gen]

Universal forwarder issues

Date filed Issue number Description
2018-04-10 SPL-153251 Universal Forwarder txz package cannot be installed on FreeBSD 11.1

Workaround:
1. Use pkg install instead of pkg add

OR 2. Install package by untarring tgz file to /opt/splunkforwarder

2015-04-14 SPL-99687, SPL-129637 Splunk universal forwarder is 7-10 days behind recent Windows Security and system log events.

2015-04-01 SPL-98978 On differing versions of Splunk Enterprise indexer (5.0.1) and universal forwarder (6.2.2), collection of the Security Event log can take increasingly longer over time.

Workaround:
To fix the problem, restart Windows on the forwarder.


2014-09-25 SPL-91279 Splunk Universal Forwarder on Windows (specifically, the splunk-perfmon.exe process) does not release key handles.

Workaround:

2015-11-13 SPL-109427 LDAP SSL no longer working in Splunk 6.3 (and later) for Windows 2003

Workaround:

The workaround is to 1) obtain Ciphers configured on Windows AD 2003 server. 2) tweak TLS_CIPHER_SUITE command in etc/openldap/ldap.conf to match it. The following is a working TLS_CIPHER_SUITE for one of the customers: {noformat} TLS_CIPHER_SUITE HIGH:MEDIUM:@STRENGTH:+3DES:+RC4:!aNULL:!MD5:!SRP:!PSK:!aDSS:!kECDH:!kDH:!SEED,!IDEA:!RC2:!RC5 {noformat}

Admin and CLI issues

Date filed Issue number Description
2018-11-07 SPL-162655, SPL-164505 Add ASNEW keyword to FIELDALIAS to support non-overriding version of aliasing

Workaround:
Avoid applying the same alias field name to multiple original field names.

If you must do this, set it up as a calculated field (an EVAL-* statement) that uses the 'coalesce' function to create a new field that takes the value of one or more existing fields. This method lets you be explicit about ordering of input field values in the case of NULL fields. For example: EVAL-ip = coalesce(clientip,ipaddress)

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

Workaround:
Navigate to a visible app, such as the search and reporting app, and access the Splunk settings pages from that app context.

2015-03-11 SPL-97942 Capability defined in an app does not take effect when assigned to a role

Workaround:
The workaround is to change the ui-prefs in ./etc/users/username/local/ui-prefs.conf to look like this:

[search] display.events.fields = ["description","except_extract_1","except_extract_2","except_extract_3","sap_order_status","sourcetype","source","status","request_mode","request_id","request_status_id","object_id","BillToCity_","Airline_","BillToName_","BillToCountry_","City_"] display.events.type = table

Workaround:
If users cannot perform operations on notable event review statuses or have issues viewing "Edit all selected" links on Incident Review, user roles must be provided with the "edit_roles" capability.
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/

2017-01-18 SPL-135260 Search formatting keyboard shortcut does not work for French language
2017-01-06 SPL-134707 Splunk restart does not create missing server.pem certificate on Windows

2015-04-24 SPL-100322 A view gets stuck with "loading" due to problematic navigation (default.xml)

Workaround:
Workaround is to use label attribute for collection element.

     </collection>  
2015-03-26 SPL-98700 splunkd Indexer crashes in IndexerTPoolWorker due to duplicated bucket id.

Workaround:
The workaround is to remove the duplicated bucket.
2015-03-25 SPL-98594 Routing events to two different groups not working as expected.

Workaround:
1 On the original UF, instead of configuring 1 s2s and 1 syslog group, configure 2 s2s groups.

2 Setup a proxy UF which takes input from the original UF and send input out syslog server. This solution only requires config change and no patch release is required.
