Just for refernece, Dominic brought this up in an earlier thread:
http://www.freebsd.org/cgi/mid.cgi?2DE61B0869B7484997BCA012845482C7EBE62DDD88@WIN2008.Domnt.abi.ca

and at least on other person seems to have the same issue...

quick question for you Dominic, do you see the correct number of routes,
but a new wrong one appear?  or does the route just simply disapear? or
does a new one seem to replace the old one?

The reason I ask is that if a new wrong one appears, it could be memory
corruption, but if a new one replaces the old one, for some reason when
allocating a new route, it could accidentatlly be replacing the default
route...

Just some thoughts...
