Although you have said not an ip conflict. I would still think there is a device in network with similar IP that is claiming it has that IP address and sending it's MAC address at some intervals. Upon failover BIG-IP GARPS out and traffic is forwarded to it. But after certain interval again that device comes into play.

 

  1. Take captures on the servers to see what mac address they are forwarding traffic to at the time of issue.

     

  2. Take capture on F5 to see if it has received the traffic sent by the server.
