system powers down after 10 hours, log says 'exiting on signal 15'

[Joachim Noreiko]

My system powered itself down after about 10 hours of operation.
The logs show that it went through the steps to shut down.
The only thing I found in the log that seemed unusual was: 'exiting on signal 15'.

A google search suggested this might be a bug in power management.
Booting with acpi=off seems to let it run without this happening.

It's done it again even with acpi=off.

Here's the lines from /var/log/syslog at the time of shutdown:

Dec 17 14:38:54 seaside-logger init: tty4 main process (4475) killed by TERM signal
Dec 17 14:38:54 seaside-logger init: tty5 main process (4476) killed by TERM signal

Dec 17 14:38:59 seaside-logger exiting on signal 15

There's nothing in kern.log at that time.
