That was my initial hunch simply because of the 6 working boards.  Our hardware designer took the board in for x-ray this morning to see if there is an issue there.  If that is the problem, then we are set - though I still plan to run some extensive diagnostics on the memory just to be sure.

Good to hear that someone has the same hunch as I did!
