This box has been up for about 12 days, running a relatively light load,
with postgresql 7.2.1 on top of ext3, which is in turn running on a
3Ware RAID controller.  It's a P3-1G, with 512M RAM and a gig of swap.
CONFIG_2GB is set.  I can provide the .config and dmesg output if
necessary.

Postgresql mysteriously crashed last night, and five oopsen showed up in
the dmesg output.  I shoved 'em through ksymoops and dropped 'em here.

I'm going to be rebooting this box with rc2aa1 tonight; perhaps that
will be an improvement.

If you'd please CC me on replies..=20

ksymoops 2.4.4 on i686 2.4.19-rc1aa1.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.19-rc1aa1/ (default)
     -m /boot/System.map-2.4.19-rc1aa1 (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.
