I'm running a Application server in a DELL POWEREDGE 8450 with 4xP-III 700
Mhz, 4GB Memory. After 40 days running kernel 2.4.14-pre6 my system reports
the following error in /var/adm/messages:

I change ther kernel to 2.4.15-pre9aa1 and today the same error occurs, one
week later, with this message:

ksymoops:
ksymoops 2.4.1 on i686 2.4.15-pre9. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.15-pre9/ (default)
-m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

26 warnings and 6 errors issued. Results may not be reliable.
In all oops the system stay up, but if you run a ps command this process
freeze.
It's possible to reboot the machine using reboot -f
Any help?
Thank's in advance
Andre Margis
