Still having swap kernel oops problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



G'day all,

Since the introduction of the 2.6.24 kernels in fedora I have had a problem where I get a Kernel Oops if I exceed physical memory. I have checked swap is on and OK etc. It works fine with 2.6.23.15-137.fc8. I have just tried the latest fedora kernel and the problem persists.

I'm at the point where I'm considering a re-install (aghast that sounds so MS) to see if that fixes the problem... but if this is a kernel problem I'd like to help get it fixed. Who should I contact to try and help fix this issue?

Cheers,
Peter.

---- Background Info ----
I have an acer 5620 core 2 duo running the x86_64 version of fedora 8 with 2GB Ram and 2GB swap. It works fine with kernel 2.6.23.15-137.fc8, but when I try any of the 2.6.24.xx-xx.fc8 kernels the machine crashes when pyhsical ram fills up. Swap is not used.

* I have checked swap space with badblocks, and all reports fine
* I have tried adding a swap file and using that, but it still crashes
* Swap is on

...$ cat /proc/swaps
Filename Type Size Used Priority
/dev/mapper/VolGroup00-LogVol01         partition       2031608 0       -1

...$ cat /proc/sys/vm/swappiness
60

at the point it crashes top (via ssh) looks like this:-

top - 14:13:36 up 29 min,  4 users,  load average: 1.32, 0.56, 0.38
Tasks: 162 total,   1 running, 161 sleeping,   0 stopped,   0 zombie
Cpu(s): 18.2%us, 6.0%sy, 0.0%ni, 43.0%id, 32.1%wa, 0.0%hi, 0.7%si, 0.0%st
Mem:   2061304k total,  2042936k used,    18368k free,    44764k buffers
Swap:  2031608k total,        0k used,  2031608k free,   679356k cached

if I run stress or memhog from the command line I do get a stack dump I have only been able to capture a bit of that by copying it by hand:-
