tmm crash when DoS protection and behavior analysis enabled on virtual server.
Traffic disrupted while tmm restarts.
This occurs when the following conditions are met: 1) Provision AFM and LTM. 2) Enable DoS protection, Behavior Analysis in DoS profiles. 3) DoS profile is associated on a virtual server 4) Bad packets are sent to the virtual server.
DoS-network behavioral analysis should be never configured since it does not provide any needed functionality. If any security dos profiles contain 'behavioral-analysis enabled', these should be changed to 'behavioral-analysis disabled.
The configuration of DoS-network behavioral analysis is no longer available, so the issue cannot occur.
