Crash in tmm when attaching a CPM policy to a virtual server.


When this occurs, TMM restarts.


This occurs when the CPM policy has a rule that uses PEM to classify action using only a category.


Do not create custom CPM rules that use PEM to classify action using only a category. To recover when the TMM is restarting, remove the affected policy from the affected virtual server, and reload the configuration.

Fix Information

Tmm no longer cores in certain instances when a CPM policy is attached to a virtual server.
