My apologies, I missed that bit of information.

Yes, there is an error in /var/log/messages.

Dec 17 11:33:07 WANemu bird: OSPF: Socket error on em3: No buffer space available
Dec 17 11:33:47 WANemu last message repeated 4 times
Dec 17 11:35:57 WANemu last message repeated 13 times
Dec 17 11:45:57 WANemu last message repeated 60 times
Dec 17 11:55:47 WANemu last message repeated 59 times

Also note that the HP NC364T uses an Intel 82571EB chipset.
