This clearly shouldn't happen in a proper LAM setup. Are you sure that
you have the same version of LAM/MPI installed on all nodes, and that the
"ring" that is found on all nodes is compiled with the same version of
LAM? Finally, you might also want to check that it works properly on one
node, e.g., "mpirun n0 n0 n0 n0 ring".
You might also want to upgrade to the latest LAM/MPI if you can -- 6.5.9.
It's been so long since the 6.3 series that I don't even remember all the
"known issues" that we've fixed since then. :-)
