我的应用（rails ruby-1.9）目前正在提供503。
所有rhc命令都无法正常工作。我甚至不能rhc ssh <my-app>。
我尝试从网上重新启动应用，它给了我这个：
Unable to perform action on app object. Another operation is already running.
Unhandled exception reference #78227deaed799856c3c386744c8be9c4: Unable to perform action on app object. Another operation is already running.
