Not quite... see below :-)

This is exactly the kind of error that I used to get when testing the
integration between SGE and LAM when SGE was not allocating enough
slots to do both qrsh-remote and qrsh-local steps.

Because SGE did not execute lamd on the remote node, so there was
nobody to call back ;-)
I bet that these are single CPU machines or SMP machines where SGE has
allocated only one slot for the job. This is a limitation of the
current SGE+LAM integration and cannot be overcome from outside SGE,
unless you give up the tight-integration and make the qrsh-remote step
be executed directly with rsh/ssh instead of qrsh, bypassing SGE.
