Each time it was in the middle of the night, somewhere between midnight and 3am. Last night it was at about 1:45am. There is no cron or at jobs set to run at this time. In fact, this thing is pretty much out of the box. We just set the network settings, and configured BIND. When I looked at it, there were a few messages on the console about named dropping some zero source packets (normal, IMHO) - and that was it. The numlock/capslock keys didn't work, CTRL-ALT-DEL didn't work, I had to cycle power. How can I start troubleshooting this? In BSD/OS there's a sysctl parameter to turn on the deadman timer, to force a coredump if the clock isn't reset every x ticks. Is there something similar in FreeBSD? sysctl -a didn't seem to indicate it.
