I was trying to do a render of a HUGE pile of .pov files using a bash
session.  When I came back the next morning, I found that the system was
locked up, and that it had essentially stopped mid-render.

I am trying to diagnose the problem.  (At first I worried it a quirk of
linux or KDE and thoroughly embarassed myself on my local LUG email list.)

So here's my current top readout when things appear to be running well.

Suppose I find another alleged system lock-up tomorrow morning and am able
to get top to run. What kinds of things could go wrong, and how would I
differentiate between a  problem in KDE's abruptly sending system to sleep,
or my use of povray using up all the memory, memory leaks, etc?

Thanks.
