Hi guys,

just noticed something weird. My FW-1 logging just started giving
some totaly bogus messages and then died. Anybody else seen this kind
of behaviour?  Not sure whether it's a local thing on my server
or something induced by a strange packet on the network.

Addresses are totaly bogus, interface is missing, port numbers don't make 
sense...

I'm running NG FP3 on Solaris.
