It looks like a new issue to me, Pasha. Possibly a side consequence of the IOF change made by Jeff and I the other day. From what I can see, it looks like you app was a simple "hello" - correct?
If you look at the error, the problem occurs when mpirun is trying to route a message. Since the app is clearly running at this time, the problem is probably in the IOF. The error message shows that mpirun is attempting to route a message to a jobid that doesn't exist. We have a test in the RML that forces an "abort" if that occurs. I would guess that there is either a race condition or memory corruption occurring somewhere, but I have no idea where. This may be the "new hole in the dyke" I cautioned about in earlier notes regarding the IOF... :-) Still, given that this hits rarely, it probably is a more acceptable bug to leave in the code than the one we just fixed (duplicated stdin)...
