This is the error -- it does not appear to be an ssh error.
I would double check that LAM is installed properly on the .204 node -- it
seems to be complaining that it can't find the process schema file, which
should probably be /etc/lam/lam-conf.lam (it was found properly on the
.203 node).
1. Can you see if this file exists on the .204 node?
2. Can you lamboot locally on the .204 node? (i.e., run "lamboot" with no
arguments, thereby booting on just the .204 node only)
