immediately after reboot, start top in an xterm,
see if any process is breeding out of control,
if so kill the root of the the processs group
next df & see if anything might be filling & a verbose log may be
exacerbating the problem.
next consider what you recently added / enabled on server
one clue, work for non 10.0 etc:
ls -ltr /var/db/pkg
(anyone know equivalent to look in local.sqlite ?)
next vi /etc/rc.conf & turn off anything optional such as mailman & majordomo
Particularly anything that runs scripts from crontab like mailman,
Years ago mailman repeatedly killed an old weak machine
repeatedly so I couldnt ssh in firring off updates scripts
that terminated After next one started, till pushing reboot
was only option.
next cd /var/cron/tabs
mv mailman [various other things , preferabl all] MV/
mv /usr/local/etc/rc.d /usr/local/etc/rc.d.MV
See if its now stable & gradually restore stuff
