[[Resetting cluster members]]
---
[Mirantis](https://docs.mirantis.com/mcp/q4-18/mcp-operations-guide/openstack-operations/rabbitmq-ops.html)
> We recommend that you do not restart a RabbitMQ node on a production environment by executing **systemctl restart rabbitmq-server** since a cluster can become inoperative.
Check `rabbitmqctl list_queues messages consumers name` if the dashboard shows a lot of ready messages it might be that there are queues where messages are being sent to but have no consumers. They expire after 30 minutes so wait for that first and then see.
A lot of unacknowledged messages on a specific node: `rabbitmq-upgrade drain` and then `rabbitmq-upgrade revive` seems to help, but in some cases the symptom moves to another node.
