Hi all,

yesterday I updated my SuSE 8.1 system with the recommended (auto) updates
through YOU. I noticed that there was a kernel update in the list, but I didn't mind.

Today, when under stress, my firewall gives hundres of messages like:

Sep 10 11:53:27 proxy1 kernel: NET: 39 messages suppressed.

Sep 10 11:54:08 proxy1 kernel: Neighbour table overflow.

I did NOT change a thing besides those updates and rebooted.
The firewall is done through iptables and configured with the "shorewall" script which
have been in use for over a year now without any problems.
Now the firewall simply stops after a certain while.

Unfotunately I cannot log in because the SSH process is crashing as well and I am
not on site, but I managed to get the logs via email.

Any hint / help is appreciated very much.


Thank you in advance, Philipp Rusch
