Deployment hangs in EAP 6 domain mode, what can I do?

Issue

• It just hangs and stays there saying "your request is being processed" in console and does nothing for more than a hour.
• JBoss CLI Hangs for deploy and Undeploy EAR, Also Deployment and Un-deployment not possible from GUI.
• We have problems in our productive environment with the master node, It is not able to detect the application and it is not able to start the context, the server.log is showing the following message, Could you help us to see what is happening?
