I've seen this problem as well, when shutting down to single-user mode,
the arp on the adapter stays active, yet no IP protocols are usable b/c
the NIC loses it's IP addresses and then refuses to relinquish control
of the carp interface to the BACKUP - This is a huge bug IMHO.
You'll also see the following spewed out to the console upon shutting
down (to Single-User mode), this appears in /var/log/messages and on the
console of the machine shut down to S.U. mode.
kernel: carp_input: received len 20 < sizeof(struct carp_header)
-E-

I just set up 2 redundant firewalls that use CARP / pfsync. I ran into the
fact that everything works fine but when shutting down the MASTER, the
BACKUP doesn't take over the states of the connections. Is that intended or
did I do something wrong? I configured my systems exactly the way the man
pages and tutorials told me and I'm not using ifstated.
What I hoped is that even the whole master can fail without being noticed
for the existing sessions.
