This can happen if you are running MPI jobs and your
mpirun/mpiexec uses SSH to launch jobs across the cluster.

The solution then is to either use an MPI stack that
can be configured to use the Torque TM API to launch
jobs (such as Open-MPI) or, if you can't do that, try
the OSC mpiexec replacement which can be built with
support for various MPI stacks and knows about Torque.

cheers,
Chris
