No, a failover wasn't involved. The real server does get a new MAC address,

Shouldn't it

the director?
know that the the VIP is for the gateway NIC
have no idea what this means. The realservers shouldn't be
arp'ing for the VIP.
How long does linux keep it's cache
about 90secs. presumably different for different kernels.
flush the arp cache on a machine with no traffic to the
other end and watch with tcpdump or arp -a to see when the
entry reappears.
and/or when does it decide to re-ARP?
every 90sec whether it needs to or not.
