Ross: I'm not used to looking at these sorts of logs. Can you summarize
a bit:

  1. Does the problem ever happen in serial runs, on only in parallel?

  2. Are you getting "just" crashes (illegal memory access/failed sync.
etc), or do you get jobs that appear to finish OK but give the wrong
result? That is, are jobs that report Etot = -2707218.6220 really
supposed to be the same as the ones that report Etot = -2709883.4871?
