I say it's time to bring out the big hammer.. oprofile. rough guide: * install the following rpms: oprofile kernel-smp-devel kernel-debuginfo * opcontrol --setup --vmlinux=/path/to/vmlinux/from/debuginfo-rpm when in abnormal state: opcontrol --start ; sleep a bit ; opcontrol --shutdown opreport -l -p /lib/modules/$(uname -r)/kernel | head -n 15 That should give you the top most consumers of processor time and hopefully some clues :-) While you're at it, run vmstat for a few seconds and study the first two columns. /Peter (who likes big hammers, everything's a nail!!) > > Regards
