I changed syncdev for syncif on our hostname.pfsync0 and rebooted. Here are those ARP errors I mentioned. It occurred booting one of our firewalls when the other one was already rebooted and had finished starting up.

But this don't represent any problem as everything works fine. I'll do some long downloads to check whether pfsync works or not.
