After G-ARP is sent, there are still two KA application messages going through ACE in both direction with mac updated (packets are seen on server and also on client site). To this point everything is fine from packet structure view. Right after, ACE sends TCP RST to client and server segment for session which was on ethernet adapter experienced a fault condition.
I have to point out that this happens if serverfarm (SF)is configured with "failaction purge" cmd. If we configure SF with "no failaction" everything works fine.
From application standpoint we need to have "purge" connection.
