Angry Unable to handle kernel paging request at virtual address fe12c000


I am running RedHat 7.1....Mosix 1.0.6....Kernel 2.4.3

We are starting to get these at least once a day on each of our nodes. I think its a Mosix issue but I'm not sure. Any input would help greatly. Here is my oops:

-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.7/ (default)
-m /boot/System.map (specified)

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?

Have you check all your file systems - that would be my first port of call. I've only ever managed to get this sorta error during hardware failures.

cheers

Yeah but

Everything seems to be functioning normally. The network may be a little slow, but everything else seems fine and I see no other errors.
Thanks,
Wayne

My kenel oops' like these were caused by an intermittent CPU failure. Took ages to track down - I ended up swapping the hardware out piece by piece then using the system for a few days to see what would happen.

cheers

Unhappy Great

Oh well,
If you run into anything else that might help me out just toss it my way. We'll keep plugging away at it.
Thanks,
Wayne P.
