TMM runs out of memory and restarts. The memory usage as shown in "tmctl memory_usage_stat", under module line tag "session" is noticed to be high, and keeps growing.
Traffic disrupted while tmm restarts.
The issue is seen when BDoS feature is configured, and if there exits Custom or Auto Generated BDoS Signatures. When such signatures exist, the BDoS one second timer callback leaks memory.
1. Disable BDoS feature. 2. Disable all configured and auto generated BDoS signatures using TMSH command: # cd dos-common # modify security dos dos-signature all { state disabled }
None
