I suggest you reboot in single user mode and fsck -fy the mount points you 
If the problem persists - you might recompile the kernel and world.

Machine locking up


                 We had a power failure at the datacenter we colocate at, 
and all our
servers went down. 

                 One is acting up ever since. It rebooted but wasn't 
accessible. I
tried to log in via our KVM and got the login/pass, but when it did the
/etc/motd and rest it locked up. CTRL-C and CTRL-\ didn't do anything. 
The remote KVM could C-A-D and the machine rebooted.

                 Once it rebooted it seemed ok, but then locked up again 
while in use.
The odd thing was I remembered to try CTRL-T, and got :

load: 0.00 cmd: login 1188 [sysctl lock] 0.00u 0.00s 0% 176k

                 on the session I was trying to log in on, and on the 
session I was
doing a tail, I saw :

load: 0.00  cmd: tail 2013 [proctree] 0.00u 0.00s 0% 0k

                 I could tab between VTYs, but logins wouldn't accept 
input, and
I couldn't C-A-D this time around. I could telnet to a special port on it
for monitoring and get a reply, but SSH/sendmail didn't reply.

                 Its a FreeBSD 5.5 (I can't upgrade it, sorry)....

                 Any clues what to look for?

                                                 Thanks, Tuc
