Hi John,

You can look through your debug log to see if there were errors adding
nodes to SGE: $HOME/.starcluster/logs/debug.log. Also when this
happens check to see if the nodes are listed in the qconf for all.q:

$ starcluster sshmaster mycluster
$ qconf -sq all.q

If you can still get this info I'd like to take a look to see what
happened.
