CumulonimbusFirst thing I'd look at 10 mins is a long time - Do you have anything on your network which holds a record for 600 seconds ?
It sounds like (And I can't verify) that a switch may not be responding to a gratuitous ARP request when the failover occurs.
When you perform a failover, do the adjacent layer 2 devices update their ARP/MAC tables ?
