Usually this is an indication that rabbitmq is no longer properly processing messages.
e.g. disk is to "full" (if you have less then 1GB freesoace or so it will stop), rabbitmq is keep running but will stop processing messages.
Have a look at the rabbitmq management interface: https://www.rabbitmq.com/management.html
This is usually points you in the right direction.
