Thought I'd throw this out there, I retraced my MTT steps and did find
that there were failures of this test back until r24774. r24775 has a
comment that looks very relevant. I am talking to the committer of that
change now.
Sorry for the false accusation.

Terry,
The test succeeded in both of your runs.
However, I rolled back before the epoch change (24814) and the output is the
following:
MPITEST info (0): Starting MPI_Errhandler_fatal test
MPITEST info (0): This test will abort after printing the results message
MPITEST info (0): If it does not, then a f.a.i.l.u.r.e will be noted

As you can see it is identical to the output in your test.

Just ran MPI_Errhandler_fatal_c with r25063 and it still fails. Everything is the same
except I don't see the "readv failed.." message.
Have your tried to run this code yourself? It is pretty simple and fails with
one node using np=4.

I just checked in a fix (I hope). I think the problem was that the errmgr
was removing children from the list of odls children without using the
mutex to prevent race conditions. Let me know if the MTT is still having
problems tomorrow.
Wes
I am seeing the intel test suite tests MPI_Errhandler_fatal_c and
MPI_Errhandler_fatal_f fail with an oob failure quite a bit I have not
seen this test failing under MTT until the epoch code was added. So I
have a suspicion the epoch code might be at fault. Could someone
familiar with the epoch changes (Wesley) take a look at this failure.
Note this intermittently fails but fails for me more times than not.
Attached is a log file of a run that succeeds followed by the failing
run. The piece of concern are the messages involving
mca_oob_tcp_msg_recv and below.
thanks,
