We have seen very unpleasant bug running OSPF on FreeBSD w/JUMBO interfaces:

The problem appears if interface mtu exceeds default bufspace for raw socket
(see sysctl net.inet.raw).

Workaround: increase net.inet.raw.maxdgram and net.inet.raw.recvspace and
restart QUAGGA.Value should be bigger than maximum MTU on OSPF-enabled interfaces

Fix required: buffer space should match interface's MTU.
