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,
