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.

EL=ALL.cust_rel

next cd  /var/cron/tabs
mkdir MV 
mv mailman [various other things , preferabl all] MV/

vi /etc/crontab

mv /usr/local/etc/rc.d /usr/local/etc/rc.d.MV

reboot

See if its now stable & gradually restore stuff
