It looks like you cannot communicate with the master node anymore. The
error message is because starcluster failed to execute a simple 'source
/etc/profile/' command with a 'connection refused' error.
Can you paste us the output of the following two commands:
> starcluster listclusters (should list status of all your active clusters
and running nodes)
> starcluster sshmaster <your cluster name> (i'm expecting this to fail)
