Symptoms

The TMM core and plugins operate asynchronously. A connection may abort and the TMM may deallocate connection context before the plugin has finished processing asynchronous events. The TMM crashes when a plugin accesses deallocated connection context.

Impact

Traffic disrupted while tmm restarts.

Conditions

Events raised during normal use of the sessiondb store may be processed after the connection context has been deallocated.

Workaround

None

Fix Information

The TMM will no longer crash.
