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.
