<p class="MsoNormal">Just today I heard from a user that he was having trouble adding nodes from the master of a StarCluster created cluster. The AMI is StarCluster public 64-bit Ubuntu EBS non-HVM (ami-765b3e1f in us-east-1). These instances have been working

<p class="MsoNormal">Running default StarCluster 0.95.5<o:p></o:p></p>
