Sometimes my FreeBSD8.0-p4 machine does an automatic reboot after
panic: page fault. (Fatal trap 12: page fault while in kernel mode)
It's at random times.
What in general can be the cause of that?
Is it always due to hardware memory errors?

What else can be a cause, how to find out ?
I have output in /var/crash but don't understand very much of it
and don't know where to look to find the cause.
please help ..
