Hi Everyone

I have been implementing a Nonblocking communication program.
(I'm using MPI_Buffer_attach(), MPI_Ibsend(), MPI_Buffer_dettach() )

The size requested for the buffer is 4096 bytes but,
the run-time error occurs,
the system displays error message " Unavailable space........."  and
abort the program.

My system platform is linux-based and 586, 32MB memory, sufficient disk
space.

Is there a limit size in nonblocking communication buffer ?
(I couldn't find the comment for buffer size )

How to resolve this problem ?
