[opensuse]  [OT] unstable system - still trying to identify the culprit. (update) I'm starting a new thread as new results have significantly changed the
situation.

I asked on the mersenne prime mailing list (where a lot of people use
mprime) if anyone had anything to add.  George Woltman (mprime author)
suggested running the "small FFT test" which would not use a lot of
memory.  He obviously had a memory problem in mind.

Well, VERY interesting results.  The machine has now been running for
almost an hour with 4 mprime instances/threads.  It's already passed
the first few selftests. 
When I started it, CPU temperature rose almost immediately to 63-64C,
then seemed to settle at 66C for a while.  It hit 67C, but has now
settled back down to 60C. 

So where does that leave me?  Is it a memory or memory controller
problem that memtest86+ fails to spot?
