A TMM process cores due to a 'valid event' assertion failure in isession_handle_evt().
An assertion failure causes tmm to create a core file and restart. Traffic disrupted while tmm restarts.
This issue can occur when a virtual server's iSession profile is modified while idle iSession connections are awaiting reuse. The iSession profile must have connection reuse enabled for this problem to occur.
Disable reuse-connection in iSession profile.
Unexpected iSession tunnel state transitions are handled without causing TMM to restart or create a core file.
