Ok, I dug up a couple of replies from Bob Manchek regarding this error,
hope they'd help you find the cause. Looks like rsh might be the culprit
here, what machines are you running on?

Hi,

What happens when you run the slave pvmd command by hand:

    rsh btrtx1 '$PVM_ROOT/lib/pvmd -s'

You should get:

    slave_config: bad args
    pvmbailout(0)
If you see something else, there will be problems.

Regards,
Bob
