freebsd stable - Apr 2006 - FreeBSD 6.1-PRERELEASE (April 5, 2006) randomly rebooting on Dell Poweredge 650

Hello All,

I'm not sure if this is the right place to be sending this or not but I 
figured I'd give it a shot.

The subject line pretty much says it all, I have a Dell Poweredge 650 box 
running 6.1-PRERELEASE which was cvsup'd on April 5, 2006.  The box has 
now twice rebooted on its own for no aparant reason.  Its a fresh install 
as well, and appears to have been doing this ever since it was installled. 
The first time the box was only up for approximently 2 days and rebooted, 
the 2nd time it was up for approximently 10 days.  I have all.log setup to 
log all syslog messages however when the reboot occured there is no 
information in the log which indicates anything going wrong...  Here is a 
small cut from the log at the time of the reboot.  As can be seen, one 
minute there is an imapd process, the next entry is the system restarting.


Apr 16 20:55:34 clearwater imapd: LOGOUT, user=XXXXXX, 
ip=[::ffff:WWW.XXX.YYY.ZZZ], headers=0, body=0, time=0

This machine previously had Linux installed on the box and did not display 
the same problems, so I'm going on the assumption that its not a hardware 
failure.

Aside from the reboots the box has been preforming extermely well.

If anybody can provide some insights or suggestions I'd greatly appreciate 
it.

Thanks,
Matt Watson

Usually, in my experience, this isn't hardware related at all (especially if
its not being logged) but rather a dying part (powersupply for example) in
your computer.

I experienced similar reboots of 6.1RC on a older Pentium III box. After
disabling ACPI the reboots stopped and the box  is very stable

[Log indicates no errors, spontaneous reboot.]

Check your BIOS settings for a hardware watchdog timer.  I had this problem 
on some brand-new servers (same class of hardware as yours) and disabling 
the timer stopped the reboots.

Intel 6300ESB, if anyone's interested.

This (freebsd-stable) is a good place to send the message.

Do you have a serial console on the box?  If not, could you try putting one on 
there?  Some kernel output, especially in the event of a crash, doesn't end
up
in the system log as (for example) the file system may not be available.  If 
you configure a serial console being logged to another machine, you can more 
reliably log crash information.  Information on setting up a serial console 
can be found in the FreeBSD Handbook, but the short of it is that you can put 
a null modem cable to another box on the first serial port, and add:

     console="comconsole"

to /boot/loader.conf.  FreeBSD will normally reboot after a kernel panic if 
debugging isn't enabled, in which case you should see the output.  And if
you
don't see output, it's probably a bad hardware interaction rather than a
kernel panic.
