[comp.sys.next] screen goes black

  I was running a large Mathematica job for the past few days and
also a Maple job via terminal on another machine.  Left last night
and things were cranking away.  When I came in this morning, the
console screen was black, and would not respond to the brightness key.
The machine was still running, although I could not find a remote
terminal to remote login to find out what was happening.  I finally
gave up and got into the ROM monitor (at least I used the usual key
strokes for it) and did bsd.  The login panel came up (very dim) after
the reboot and the brightness key worked again.  I don't think I
could have run out of space (there was over 300 MB of space for swap).
Did something get hosed? Monitor seems fine now.  Room wasn't hot
and the power was steady last night they tell me.  So what happened?
I didn't really lose any data, but did lose a lot of time.  Has this
ever happened to any of you?
