Here is the uname -a output: FreeBSD vader.immure.com 10.3-STABLE FreeBSD 10.3-STABLE #15 r313997: Mon Feb 20 14:40:00 CST 2017 bob@vader.immure.com:/usr/obj/usr/src/sys/GENERIC amd64 At first I suspected that it might be the power supply as it was a couple of years old so I replaced that. Unfortunately, it has begun doing it again (had a couple of weeks respite) so now my suspicions seem to have been incorrect. I was hoping that someone might be able to give me some clues on what I can do to reveal the problem. Are there any general debug settings for the kernel (or elsewhere) that would maybe give an indication of why it is being rebooted (assuming it's a software problem)? Thanks for any suggestions you may have! Bob -- Bob Willcox | If a program is useful, it will be changed. bob@immure.com | Austin, TX |
