>Description:

On 4 August 2004 the machine unexpectedly shut down and rebooted.  The
only logs are as follows:

Aug  4 09:01:40 lazarus kernel: Shutting down daemon processes:

followed by user processes and syslog notifying of SIGTERM.

The system came back up 2 minutes later with filesystems marked as clean.

On 11 August 2004 the machine did the same thing:

Aug 11 14:01:29 lazarus kernel: Shutting down daemon processes:

followed by the same process messages.  System came back up clean.

kldstat shows
Id Refs Address    Size     Name
 1    7 0xc0400000 368cdc   kernel
 2    1 0xc0769000 50dbc    acpi.ko
 3    1 0xc45cc000 19000    linux.ko

so it's possible that it's acpi doing it.  There are no temperature
sensors on this motherboard, but I have sensors on the disks, and
they show the following temps immediately prior to shutdown:
(temps in C, 4 disks probed).


Aug  4 09:00:01 lazarus root: temperature: 33 36 31 36
Aug 11 14:00:01 lazarus root: temperature: 35 36 32 38

The processor is a 1GHz P3 with its own fan (confirmed operational).

>How-To-Repeat:

It appears that this might be a weekly thing, but I only have two
datapoints.  There's nothing in cron that would cause this.
>Fix:

Unknown.  What I'd really like is a way to turn on logging that would
help pinpoint the problem.  Is there any way to rule out acpi?  Any
other suggestions for logging / forensics would be great.
