Help with silent reboot of 10.3-stable system

[Jan Knepper]

Is your system swapping to disk? Heavily?

Might want to check the swap space on disk.

I had spontaneous reboots some years ago because of bad swap space on 
disk. (Got a new disk, 'dd'-ed the old disk to the new disk, reboot on 
the new disk and everything was fine)
