[BlueOnyx:03378] Re: Troubleshooting lockups/crashes

[Darrell D. Mobley]

I am still chasing my tail on the server listed below.  For no apparent
reason and with not much evidence to go on, the server just stops responding
to anything but pings all on its own and requires a reboot to get back
online. Below are the last items I can confirm occurred on the machine
before it locked up and stopped responding this AM:

Jan 20 02:40:45 web1 syslogd 1.4.1: restart.
Jan 20 02:41:01 web1 crond[24780]: (root) CMD (/usr/local/sbin/dfix.sh)
Jan 20 02:41:03 web1 dovecot: pop3-login: Login: user=<site12>,
method=PLAIN, rip=216.17.175.95, lip=208.77.219.98
Jan 20 02:41:04 web1 dovecot: POP3(site12): Disconnected: Logged out
top=0/0, retr=0/0, del=0/0, size=0
Jan 20 02:41:10 web1 cced(smd)[24997]: client [0:24996] has admin rights

Nothing beyond 02:41:10 appears in any of the logs.  

SSH connects but times out.  Telnet 110 and 587 appears to connect, blanking
the screen, but echos nothing. DNS appears to be up as pinging to domains
hosted on the server returns IP address ping times.  It has to be locked up
though because the logs stop at the time of the lockup and don't restart
until rebooted.

Any ideas would be welcome.
