Sorry for an email again...but I was too ambiguous in my previous email perhaps.

I am trying to run a program, rather multiple copies of a program on MPI. There is no message passing between various processes within the communicator.
I am using data-structures in the program that could be heavy on the memory.

Here is the a trace of the program:
 
$mpcc -o part partition.c -lm -lmpi
$mprun -np 2 exefilename
[3472 MPI_COMM_WORLD 2]ERROR in MPI_Finalize: low level communications error: Invalid argument: too many failed connects from wor*** to trux*** using interface "hme0" possibly due to network problems. Please notify your system administrator.
Fatal error, aborting.

[3472 MPI_COMM_WORLD 1] ERROR in MPI_Finalize: low level communications error: Invalid argument: too many failed connects from golds*** to tru*** using interface "hme0" possibly due to network problems. Please notify your system administrator.

Signaled.

I would really be glad if someone who has faced this error could revert back to me.

Thanks,
Sourabh
