Did you clear the arp table on the firewall after configuring MAC Masquerading? Sounds like the firewalls are dropping the gratuitous ARP, as they should, which is why you should be using MAC Masquerading. It sounds like for a short bit the MAC of the standby unit was learned by the firewalls, and needed to either be cleared or wait for them to timeout.
