Newbie: system spontaneous reboot

[Gary Schenk]

My new FreeBSD system seems to be working well. When I logoff my user account, 
I leave the machine on to process setiathome. Several times in the last week, 
I return to find a fatal trap message on the screen, at the end it states 
automatic reboot in 15 seconds, press any key to cancel. It has not rebooted 
but it is merely waiting. When I press a key, it reboots.

I'd like to know if any one knows what the problem is. I'd also like to know 
how to copy or capture the screen  message to a file so as to post it to this 
list. I am running FreeBSD 4.7-RELEASE on a dual boot setup with Win98 on a 
600MHz Pentuim 3 with 128 meg RAM. This is my third installation of FreeBSD 
on this machine.

Thanks.
