A few days ago I restart in an "automatic" one server HP ProLiant DL 120 G5, you have installed SLES 11 SP1, I did not find the reason. only in the /var/log/ message shows:

'myServer pm-profiler: Power Button pressed, executing /sbin/shutdown -h now'

Searching the web, I could guide the search to something associated with apci, but nothing conclusive. acpi log increase but honestly I do not notice increased log in /var/log/acpi.log.

In that should focus the search for this error?
Thank you.
