--------------------------------------------------------------------------
It looks like MPI_INIT failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during MPI_INIT; some of which are due to configuration or environment
problems.  This failure appears to be an internal failure; here's some
additional information (which may only be relevant to an Open MPI
developer):

  orte_grpcomm_modex failed
  --> Returned "Data unpack would read past end of buffer" (-26) instead of "Success" (0)
--------------------------------------------------------------------------
*** The MPI_Init() function was called before MPI_INIT was invoked.
*** This is disallowed by the MPI standard.
*** Your MPI job will now abort.
[localhost.localdomain:25369] Abort before MPI_INIT completed successfully; not able to guarantee that all other processes were killed!
