Rare ARP problem

[Troy Hakala <troy@xxxxxxxxxxxxxx>]

In an LVS-NAT setup, on a rare occassion, the ARP cache of one of the real
servers gets the wrong MAC address for the director, I assume after a
re-ARP. It gets the MAC of eth0 instead of eth1. It's easy to fix with an
arp -s, but I'd like to understand why this happens.

Thanks!
