Hi:

All of a sudden, I'm now seeing this error when I try to run a starcluster:

Here's the trace of "starcluster -s" -- with 4 nodes:

>>> The master node is ec2-75-101-184-68.compute-1.amazonaws.com

If you could help me clear up what is going on, that would be great.
(Note, I CAN ssh in to the nodes, but my user account, with my EBS volume,
is only getting mounted on the master node, and none of the slave nodes ...
so I can't do anything.)

Thanks,
Dan
