Hi Albert Graham!

I do not know that I make the cut of "highly technical" but when I
hear "fail under heavy load" I first think of heat.  It might be
interesting to make a little chron job which simply logs CPU and MB
temps every minute or so.  Maybe check the sink (well seated??).

I am in the process of making a little script to snap a picture of
what is going on in /var/log (and many parts of the machine as well).
I will post here when done if it still seems appropriate.

For the truly dedicated to knowing "WHY?" The Linux a crash dump kit:

# One of many!

Good Hunting!
