Ahhh... actually, I noticed mbuf memory error with one of these:
# netstat -s -p carp
carp:
3112793 packets received (IPv4)
0 packets received (IPv6)
0 packets discarded for bad interface
0 packets discarded for wrong TTL
0 packets shorter than header
0 discarded for bad checksums
0 discarded packets with a bad version
1347685 discarded because packet too short
0 discarded for bad authentication
0 discarded for unknown vhid
0 discarded because of a bad address list
4512672 packets sent (IPv4)
0 packets sent (IPv6)
8589 send failed due to mbuf memory error
391 transitions to master
And also increasing the carp logging I now see:
Feb 1 13:50:02 fw1 /bsd: carp: carp1 demoted group carp by -1 to 0 (<
snderrors)
Feb 1 13:50:04 fw1 /bsd: carp0: state transition: BACKUP -> MASTER
Feb 1 13:56:48 fw1 /bsd: carp: carp1 demoted group carp by 1 to 1 (> snderrors)
Feb 1 13:56:48 fw1 /bsd: carp0: state transition: MASTER -> BACKUP
So how do I go about debugging this?

I tried adding this, no effect. I also tried removing IPv6 from the interface
as
someone suggested, but that didn't help either it seems.
