Fatal trap 12

[Daren Desjardins]

Over the weekend my bsd 4.9 apparantly rebooted for kicks by itself,
reporting a fatal trap 12 in messages. I looked through the list history
and found some posts indicating it may be a memory issue. Im hoping
someone can confirm/deny this for me so I know how to start tracking
this down. The machine had an uptime of over 20days prior to reboot, it
happened at 3am which is shortly after the daily cronjob is suppose to
run. I never recieved my daily report that night either.
