When tmm is under heavy load it may run out of memory and crash under certain conditions.
Traffic disrupted while tmm restarts.
This occurs when the following conditions are met: 1. Packet classification is enabled 2. Security logging profile is used with 'log translation fields' option enabled. 3. Fast flow forwarding is enabled on forwarding virtual server.
To work around this, do one of the following: -- Disable 'log translation fields' in the security logging profile. -- Disable fast flow forwarding.
This fixes a memory leak when TMM is overloaded and forwards flows to the peer, and packet classification is enabled with 'log translation fields' in the logging profile.
