Thanks Bill. I'd suspect the switch too except that all 3 carp interfaces are on the same physical interface in this case, yet it's only carp0 that experiences this behavior. Nevertheless, I will haul out tcpdump and see what's going on. To answer your question, no, pf is not running on these boxes. I also have two 3.7 CARP/pfsync firewalls that have never exhibited this behavior and they are on the same switch. Tim
