On ACE arp failed to real servers and service all stopped. Only reload the module could recover the service. It seems mostly caused by FT. And ensure you can able to ping the gateway. Also make sure any access list is blocking or not.

It looks like you don't have FT (alias & peer IP's) set up.

If the second ACE still can't ARP or ping the gateway after you get that taken care of, check w/ TAC to see if you're hitting bug CSCsz50968.

We ran into it when we were doing a bunch of failover tests between the two VSS chassis.
