1) What jw354 said.

2) Are you sure the servers are hashing differently?  Can you find out
   what the 'secs' field indicates (I suspect it's greater than 3)?

Anecdote) ISC DHCP 3.0.x identifies failover relationships by the peer's
	  IP address (!), which means you can't have more than one
	  failover relationsihp between two individual IP addresses.
	  ISC DHCP 3.1.0 (correctly) identifies failover relationships
	  by the relationsihp name.
