Error in MPI_File_open

[Aroma Mahendru]

Okay I get this error :

MPI_File_open: MPI_ERR_OTHER: known error not in list
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
--------------------------------------------------------------------------

So, does this mean there is an older version of openmpi ?The version on the
cluster is Open MPI 1.5.4.
