Severity: 2-Critical


When a session is deleted for a reason unrelated to explicit admin action, a generic log message appears: 'Session deleted due to user inactivity or errors.' The message does not distinguish user inactivity from 'error', so the log message indicates a possible error when perhaps none had occurred.


Cannot troubleshoot a session termination cause because there is no ability to determine whether the session was deleted because of normal user inactivity or due to some other cause.


Normal user inactivity is indistinguishable from numerous other causes related to policy actions.



Fix Information

The session deletion cause has been added as an enhancement to the session deletion log functionality.
