Hi,
My linux box keeps crashing every 24 hours or so. It's running kernel version 2.4.21. I ran the oops message through ksymoops and got this result:
ksymoops 2.4.9 on i686 2.4.21. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.21/ (default) -M (specified)

What could be the problem? Any help would be highly appreciated.
Thanks.
