Lenny, I opened a ticket for something that looks the same as this.
Maybe you can add your details to it.

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?
Yep, it is simple hello application.
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)...
It is not so rare issue, 19 failures in my MTT run
(http://www.open-mpi.org/mtt/index.php?do_redir=765).

The error is not consistent. It takes a lot of iteration
to reproduce it.
In my MTT testing I seen it few times.
Is it know issue ?

Pasha
