I do no have this problem on my cluster.  I used to have it, but fixed
it by hacking mpich to not create its own process group by default. 
There's also a similar fix you can do in the submit script.

Is this script in tcsh?  If so, try adding the line:

before your call to mpirun.

One note, I don't use the myrinet extensions, so I'm not sure if that
will change things or not.
