I have a centos vps (Parallels Virtuozzo container) which has been running for months. However, a few days ago it started to randomly reboot itself, and i can't find out why. And the biggest problem that i don't understand is that it takes 40 minutes to reboot (as far as i can see in the logs)
root ~ # cat /var/log/messages | grep shutdown
Oct 11 13:52:11 vps27 shutdown[23968]: shutting down for system halt
Oct 14 14:55:17 vps27 shutdown[30662]: shutting down for system halt
Oct 15 06:21:23 vps27 shutdown[20157]: shutting down for system halt
And notice the time difference between shutdown and xinetd's start:
Oct 15 06:21:23 vps27 shutdown[20157]: shutting down for system halt
Oct 15 06:21:24 vps27 init: Switching to runlevel: 0
Oct 15 06:21:27 vps27 saslauthd[30614]: server_exit : master exited: 30614
Oct 15 06:21:38 vps27 named[30661]: shutting down
Oct 15 06:21:47 vps27 exiting on signal 15
Oct 15 07:04:34 vps27 syslogd 1.4.1: restart.
Oct 15 07:05:06 vps27 xinetd[1471]: xinetd Version 2.3.14 started with libwrap loadavg labeled-networking options compiled in.
Oct 15 07:05:06 vps27 xinetd[1471]: Started working: 0 available services
And here's what Parallels Power Panel says in terms of Status Changes:
Time Old Status Status Obtained
Oct 15, 2011 06:23:46 AM Mounted Down
Oct 15, 2011 06:22:31 AM Running Mounted
Oct 14, 2011 03:06:48 PM Starting Running
Oct 14, 2011 03:06:23 PM Down Starting
Oct 14, 2011 03:06:08 PM Mounted Down
Oct 14, 2011 02:58:24 PM Running Mounted
For some reason it's getting into Mounting mode and then restarts itself.
The only problem that i can imagine is disk space utilization, which is now 84%. But can that be a reson for system halt?
