Linux netfilter shuts down the server

Linux netfilter shuts down the server

[Lutfi ODUNCUOGLU]

Hello,

I have a sun x1400 series server, that I use as a router. The OS is
Debian Squeeze and every week my router goes down and I cannot do
anything then hard booting the server. The photo of the error messages
can be seen at http://metu.edu.tr/~lutfio/a.jpg. What may be the problem?

Thanks,

Lutfi

That information is incomplete. We need to know what Linux kernel
version you're using, and the upper part of the backtrace would be
really helpful.

Ok. I am using custom compiled 2.6.37.2 AMD 64 bit kernel. For upper
backtrace issue when I hard boot the server, I can't find any logs about
this error. Is there a way to have this backtrace for next time?

Thanks,

Please try to setup netconsole so that another machine in your lan can
get a copy of full backtrace, because your screen is too small to get it
all.

Hello,

Server has gone down tomorrow night as I mentioned. I got backtrace logs
with netconsole, you can see the log below.

We did many changes in net/ipv4/inetpeer.c in last kernels, not yet
backported to 2.6.37.X

You could try to backport commit 686a7e32ca7fdd8 (inetpeer: fix race in
unused_list manipulations)
