If an AFM DoS profile with Behavioral Analysis enabled is applied to a virtual server configured for state mirroring, TMM may crash on the secondary device with a SIGFPE panic. The system may produce a panic message in /var/log/tmm* similar to the following: panic: ./local/net/packet.h:505: Assertion "l3hdr set" failed.
TMM crash: Degraded HA. Traffic disrupted while tmm restarts.
AFM is provisioned and an AFM profile with 'Behavioral Analysis' enabled is configured on a virtual server, and that virtual server is configured for mirroring.
Enabling the 'Behavioral Analysis' feature in an AFM profile is not completely functional at this time. Please do not enable the feature.
AFM is provisioned and an AFM profile with 'Behavioral Analysis' enabled is configured on a virtual server, and that virtual server is configured for mirroring now works as expected, and does not result in a TMM crash.
