Could this be a bug in preemption? Has anyone else successfully set up
carp with preemption? My OS is now OpenBSD 3.8 RELEASE. After going to
stable, I'll be back! :-)

This past weekend I implemented a pair of 3.8 (right of CD) carp/pf firewalls in a production role. They are working great. I can be watching movie trailers and while the trailer is still downloading I can 'ifconfig rl0 down' on the active node and poof things fail over. The trailer keeps downloading. 10 seconds later I can 'ifconfig rl0 up' on the now backup node and within seconds it becomes the active node again. The trailer keeps downloading and playing.
