Several times after some boxes of mine crashed, they kept crashing every day or every few days. Only solution is to reboot in single user mode, fsck the filesystems (notice, not "fsck -p") and restart. I guess softupdates let something bad slip through and won't fix it at reboot. Just my 2c. bye av.
