Are you sure that you're using LAM/MPI? That error message does not
appear in our source code anywhere.
I *do* see this error message in the ROMIO source code (in parts that
are not used by LAM/MPI), which leads me to believe that you are using
MPICH. If this is the case, you'll need to contact the MPICH
developers for support.
Thanks.
