A couple of messages that i read when searching through google
appear to indicate that it might rely on your firewall, bad
packets that are not in state anymore and such and then gets
blocked by your firewall.

Could you provide some more details of events happening around
the same time of the messages you posted here? Perhaps something
else precedes the message which gives more information on what
might have happened...

Url with some information:
