 Posted: Sun Aug 07, 2005 11:29 am Post subject: kernel bug in mm/vmscan.c whenever swap is heavily used |
 |
|
Hi all,
I have problems with system hangs and seemingly random program abortions. As I concluded from the logs appended below, the problem is probably related to kernel swap handling. The system comes up fine and idles around nicely, but as soon as I actually start using it, I have only a few minutes until it either hangs completely, or programs terminate abruptly with segmentation faults.
As a workaround, I have disabled swap completely. Since then (24h), the system runs stable (under full load, intentionally). Does anybody have an idea what I can do to make swapping work stable?
My system is a Shuttle SN25P barebone with nForce4ultra chipset, Athlon64 3500+ with 1Gb ram, a 2Gb swap partition on a 300Gb sata drive, running kernel 2.6.12-gentoo-r6. Just in case, here is the output of 'emerge --info'.

Here are the snippets from /var/log/kern.log leading to the last crash before I turned off swap. I was just playing around with some programs while an scp was running, then everything went black...

I have the same issue. It always seemed to be a random lockup, I couldn't figure out any reason behind it. Then today I was watching my memory usage, and as soon as the memory got filled with caches and whatnot, boom. That was it. I managed to capture the kernel output from a serial console and I have almost the exact same message as the guy above. I'm also using kernel 2.6.12-gentoo-r6 on an Athlon64 machine with 2GB of RAM and SATA hard drives. The swap is on a SATA drive.
