Message-ID: <3FC6E0FC.6060604@skyweb.co.ke> (raw)

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.
