That's the problem. We'll have to figure out where does it come from. Could you share your routing table? Doing "# netstat -rnf inet" How does your /etc/hostname.carp1 look like? Do you see an error when running "# sh /etc/netstart carp1" ? If you grep for 'arp' in /var/log/messages do you get anything?
