Symptoms

With an iRule that runs the STATS::set command inside the ACCESS_SESSION_CLOSED event, tmm cores.

Impact

Traffic disrupted while tmm restarts.

Conditions

STATS:: command invoked inside the ACCESS_SESSION_CLOSED event. This event does not have all of the connection information so invoking STATS:: to store data from the connection will fail and cause tmm to crash.

Workaround

Do not use STATS::set inside ACCESS_SESSION_CLOSED

Fix Information

None
