--- Comment #2 from patfbsd@davenulle.org ---
Hello,

I think your problem is that your advskew values are very near (80 and 90).

Use something like 0 (preferred master) and 200 (preferred backup)

When enabled, pfsync increments carp.demotion when starting the bulk
synchronization of the states, but pfsync is started after carp and pf. So
there is small lap of time between the two and your firewall can became mas=
ter
between the two.

Anyway the lap of time should be small and the backup should become master
again until the bulk is finished.

Check the logs of carp in /var/log/message

It is hard to say if there is a bug or not, you can ask on the FreeBSD mail=
ing
lists for help.

Regards.
