bird generating 600Mbit traffic

[Arkadiusz Miśkiewicz]

Hello,

bird (1.3.10, earlier versions too) sometimes starts flooding my network with 
ospf packets, generating over 600Mbit of traffic.

tcpdump shows traffic between two bird machines, problematic one sends LS-
Request then receives LS-Update, asks Request again, receives LS-Update and so 
on.

Any ideas on what could be the reason for such behaviour?

Thanks,
