Ok, so we are seeing this:

Nov 20 00:10:51 blah-101 dhcpd: DHCPACK on blah to 00:15:70:89:6d:00 via blah
Nov 20 00:11:32 blah-101 dhcpd: timeout waiting for failover peer failover
Nov 20 00:11:32 blah-101 dhcpd: peer failover: disconnected
Nov 20 00:11:33 blah-101 dhcpd: failover peer failover: I move from
normal to communications-interrupted

I think that my packet capture got this event, so I'll have a look...
