Subject: Buffer too small in MPI_Recv?

I got the follow error message running MPI on SP2:
  1:ERROR: 0032-117 Buffer too small  (39072) in MPI_Recv, task 1
  2:ERROR: 0032-117 Buffer too small  (39072) in MPI_Recv, task 2

It seems to me that MPI only talks about buffered send, MPI_BUFFER_ATTACH
applies to MPI_BSEND. What I can do with this MPI_Recv buffer too small case?
Adding MPI_BUFFER_ATTACH to attach a large buffer doesn't help. Thanks very
much.
