Yes but I DO have a default route.. I tried putting one in, removing it, putting it back, rebooting.. The problem is ZEBRA listens to the socket and uses 10-15% cpu because of these messages.. It doesn't happen on -RELEASE though so hmmmm.. I guess I could hack it to skip over the reporting of the message.. probably be good in the future, but something is wrong because I've added a default and removed it also so maybe something with the -STABLE code that changed something in the routing area..
