bird 1.3.8 vs 1.3.6

Hi! Is there something with these versions that is not compatibly with each other for the ospf to work in ipv6? Right now I have a bird 1.3.8 instance neither announce nor getting an routes in a area. It is stuck in the exchange state. The ip4 versions also get stuck in the loading state for a while and then continue. (during the loading state the routes are announced to the others - so it's working somewhat). -- //fredan
