Rec'd ARP request collision from 10.1.1.4/0022.5237.9c62 on interface insid

Have pair of ASA5550 firewalls linked as failover pair. Getting the above message in the logs every few mins. The 10.1.1.4 address is the inside interface. Does this message mean that there's a mismatch in the arp cache for this mac address (ie it has more than one related IP addresses) or what ? Thanks in advance

The best method to make one FW the primary one is to log into it and issue the failover active command and use the write standby while logged into the primary one to sync the configs.

The commands are on the link as well: http://tinyurl.com/6du7l7
