<p style="margin: 0px;">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
reliably this way for many months, so it seems like something has changed at AWS? Anyone know of anything?<o:p></o:p></p>
