Bizarre - it works perfectly for me. Is it possible you have stale
libraries around? Or are attempting to connect to older versions of
mpirun?

You might also try cleaning out any old session dirs just to be safe -
my best guess is that you are connecting to an older version of mpirun
and getting an incompatible response.
