If you have more than one processor core per node, and the problem only
occurs when you use more than one process per node, then try adding

-mca btl_sm_num_fifos 16

to your mpirun/mpiexec/orterun command line. Replace "16" with a number
grater than or equal to twice the number of processes per node.

Open MPI has this bug with certain compilers :
