    I have been getting sporadic errors from a code running
on the IBM SP-2 using IBM's implementation of MPI.

    The error message is:

ERROR: 0032-114 Internal error:  Handle is already being waited for in
MPI_Barrier, task 1

The error usually does not recurr if I rerun the program.

The program uses MPI_Barrier and MPI_Isend, but not MPI_Irecv.

Does anybody know what is going on here?  (The user consultants
for the system I am using don't.)
