One simple thing that has bitten me with freevrrpd is the link monitoring.
If the link on an interface is unstable ( bge being the usual suspect in
our case ) then freevrrpd will stop doing vrrp announcements.
This is to stop things like broken utp or duplex mismatches from causing
major mischief. However if its normal for your nic's to be borking then
you'll have to "fix" the code in some fashion.

The current freevrrpd code might be a bit different, but this is
what I encountered with fbsd/bge about a year ago.
