removing primary ip address on ospf interface

[Martin Kraus]

hi. what happens to bird when you remove a primary ip address on an ospf
interface? it seems that bird crashes. 

all i can find in log is

nl_get_reply: Ignoring out of sequence netlink packet (7189e0 != 7189e1)

and then some ospf and kernel route messages and then bird starting 6 minutes later
when my colegue managed to log into the router and start it. 

anyone got a similar problem? is it a problem with bird or is it just stupid
to remove a primare ip address on an ospf interface?

thank
mk
