Hello,
It took awhile for the next oops to appear. I modifed my boot procedure by turning off swap with "swapoff -a" and allowed the system to run. I waited until all of my 1.5GB of physical RAM was allocated (cached or in use), and let the system to contiue to run. The system ran stably for 2 days with normal use. I then switch swap back on with "swapon -a".
I monitored VM usage with "vmstat" occasionally. VM paging was 0 in and 0 out up to about 2 hours before this latest oops.
Here is the oops log:
ksymoops 2.4.8 on i686 2.4.19. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.19/ (default) -m /boot/System.map-2.4.19-hm (specified)
