Severity: 3-Major


Internal events might not be handled properly, and might cause issues leading to traffic disruptions or a TMM process crash.


This might cause a temporary inability to pass traffic through the BIG-IP system. This issue might also result in tmm cores and crashes.


For example, this issue might occur due to a timing issue with iRule 'after' and 'session' commands.



Fix Information

This version provides handling for session callbacks and timer events such that the tmm core and crash no longer occurs.
