How > to trouble shoot, Please shed some light on it. 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. http://www.berklix.com/~jhs/src/bsd/fixes/FreeBSD/ports/gen/mail/mailman/files/patch-crontab.in.in.R 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 PS I've now started reading your http://pastebin.com/Td2JetmK Cheers, Julian -- Julian Stacey, BSD Unix Linux C Sys Eng Consultant, Munich http://berklix.com Interleave replies below like a play script.
