Hi,

Iam getting very frustrated with this problem... I attached the kernel log below. This happens out of nothing. The router is running 24/7... If I run a huge service like squid,I can make it go faster, but not immediately.
The system is: Asrock P5b. Celeron E340, 1GB RAM, 2GB Swap. 1 HDD, 450W PSU
I have 2 units running on the same hardware, but this on e is the only one that hangs every now and then
The only thing I understand from belows log is "out of memory, killing process XXX" but its all low mem processes.
The router is behind another router/Firewall, so I doubt its some outside attack.
log:
Code:

These problems can be very difficult to diagnose. It could be a memory error is corrupting a running program (which them acts goofy and consumes RAM until the kernel kills the process).


I would try running Memtest86+ for a few hours..

Other things I have tried are re-seating RAM chips and swapping power supplies, both of which a re hardware problems that can lead to odd symptoms.

Finally, you can try a complete reinstall, just in case the something got corrupted some how.

Good luck!

I agree with everything Vorlon said ... except for reinstall. You can do emerge -e, if it fails the same way you do have a hardware (likely RAM) problem.

Maybe you have a bad memory leak. You can run within a screen session
Code:
top -b >> /var/log/top.log

to monitor memory usage of each process. If the last entries before a crash don't show anything suspicious, I agree that you probably have a case of bad RAM.

thanks for the hints, running memtest was my next plan. I was hoping some more info could be read from the log..

I'll run the top -b first and see if it happens again.

Soo,

I made some more tests... :-)

I ran memtest for 6hrs but no problem found.

I figured that the system is still running fine, but networking is down completely. (Both cards)

I made a short hourly cronjob

Code:

echo  $(hwclock)" | "$(ping -c1 192.168.123.150)" | "$(ping -c1 192.168.100.151) >>/log


And it reports no network strangely enough on a time where no network action was present. I guess this isn't some load related issue

What could make the ethernet subsystem fail completely? Wrong kernel configuration??
