EC2上的Starcluster ubuntu停止了工作。我不知道任何故意的配置更改或其他任何事情，我无法找到太多帮助。如果有人有任何建议，你能告诉我吗？启动，终止甚至列出群集都是错误的。以下是我尝试列出群集时出现的错误：
ubuntu@ip-10-29-249-203:~$ starcluster listclusters
StarCluster - (http://star.mit.edu/cluster) (v. 0.94)

您使用的是哪个版本的StarCluster？它是最新版本还是最新的开发版本？
如果我查看最新开发版本的错误，则会引用此行：
我的猜测是您的群集别名标签存在问题。在任何情况下，甚至终止集群并启动新集群并不能解决问题，这是非常奇怪的。
如果您发现更多内容，可以重现问题或需要更多帮助，您也可以使用StarCluster邮件列表。 http://mailman.mit.edu/mailman/listinfo/starcluster
