Can you please help me with this problem?

I am trying to run OpenFOAM 2.2.x in parallel. I am working in a Centos 5 supercomputer.

I am trying to run a very simple case from the tutorials called damBreak in parallel. And when I type:

mpirun -np 4 interFoam -parallel

The following error pop up:

It looks like opal_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during opal_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

opal_shmem_base_select failed
--> Returned value -1 instead of OPAL_SUCCESS
