Good evening. Faced with the problem: at some point the message broker "floating" (stopped updating the web interface and make the connection). When you try to restart rabbitmq-server start command process stops responding after the message output:

Prompt, as fixed a?
P.S. Command systemctl status rabbitmq-server.service printed:
