Hi,

I have a colo machine running RELENG_5_3 (without serial console access).

Sometimes the machine will not come back up after a reboot.

Since there is no console, I have no idea what/why/how... :-(

This is in the log file:

May 10 16:11:54 europa reboot: rebooted by chacs
May 10 16:11:54 europa syslogd: exiting on signal 15
May 10 19:26:52 europa syslogd: kernel boot file is /boot/kernel/kernel
May 10 19:26:52 europa kernel: Copyright (c) 1992-2004 The FreeBSD...

(okay, I just found out how to do /var/log/console.log)

My question is, is there some kind of "watchdog" type of 
program/settings which will trigger a "forced" reboot should the 
shutdown part of the regular reboot process failed ?

Regards.
