Applicability

Splunk Enterprise

Description

Splunk web is returning HTTP 500 internal server error after entering the login credential because splunkd fails to start up due to parsing error.

Investigation

Splunkd fails to start due to parsing error of the web.conf:tools.sessions.timeout attribute.

$SPLUNK_HOME/var/log/splunk/splunkd.log shows the following error:

ERROR UiHttpListener - Can't parse tools.sessions.timeout value "240s", using default of 60
Note: Only integer value is allowed.

Note: web.conf:tools.sessions.timeout attribute requires an integer value.

Resolution

The HTTP 500 internal server error is resolved after correcting the timeout value to the default value of 60 in web.conf to allow splunkd to start successfully.
