Opened: Oct 26, 2016
Severity: 2-Critical

Symptoms

There are no visible functional issues. But when the APM end user clicks the logout button or hangs up on the the client, the server (tmm) doesn't delete the session immediately. The session will later get deleted as part of the session timeout.

Impact

Sessions won't get deleted immediately but will get deleted eventually depending on the access profile timeout. There might be memory pressure based on the load.

Conditions

New APM client on an older BIG-IP release.

Workaround

Write an iRule to delete sessions based on the uri/query param.

Fix Information

None
