Hi Aviv,

 

There could be many reasons to LB fail-over, based on what type of fail-over setup you are running in your environment. What did you see in /var/log/ltm?

 

  • If you have "network fail-over" setup, it could be caused by lose heartbeat, Search for "high availability daemon_heartbeat" in logs.
  • If any daemon is failed, check what is configured as failed triggered action.
  • And more...

Anyway, /var/log/tmm and /var/log/ltm can reveal the truth.

 

Regards,
