As subject, decoded BUG below.
Given the time that this occurred, the machine was probably doing
the daily cleaning for postgres. It was almost certainly without
significant load at the time (it's not really a production machine).
It appears still to be running without any problems.
I can supply other information on request.
Hugo.
ksymoops 2.4.5 on i586 2.4.20-ac1. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.20-ac1/ (default)
-m /boot/System.map-2.4.20-ac1 (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.
