Resource-based flow control should only block publishers. Re-creating connections
won’t help: every publishing connection will be blocked. Consumers should not
be blocked but nearly running out of disk space sounds alarming and can prevent
RabbitMQ from moving messages to disk or very heavy OS paging .

What’s in RabbitMQ log? There should be disk and RAM alarms logged. rabbitmqctl status
indicates disk limit alarm should be on.
