Seeing a funny problem. Whenver the secondary ASA is rebooted, there is complaint of an ARP conflict on the failover interface:
Received ARP request collision from 169.254.0.1/1cdf.0f2e.e8b6 on interface FAILOVER with existing ARP entry 169.254.0.1/1cdf.0f2e.e0b0
169.254.0.1 is the primary ASA's failover interface, and the physical interface has MAC address 1cdf.0f2e.e0b0
169.254.0.2 is the secondary ASA's failover interface, and the physical interface has MAC address 1cdf.0f2e.e8b6
Failover IPs should remain constant even as roles change, so I'm very puzzled why the secondary would take the primary's IP.
Both are single context running 9.0(3)
