[rabbitmq-discuss] RabbitMQ couldn't recover after the free disk space went below the default threshold limit

It looks like two hours after you went under the disk space limit, you 
actually ran out of space. RabbitMQ will in general not handle 
out-of-space very well (which is why the limit is there).

While the disk space alarm will try to stop RabbitMQ from using any more 
disk by blocking publishing, there is nothing to stop other applications 
continuing to eat disk space until you run out. The disk space alarm 
will not guarantee you will not run out of disk space.

Furthermore, before version 3.2.0 RabbitMQ could decide to page 
transient messages out to disk even after the disk alarm went off. In 
3.2.0 and later RabbitMQ will ignore memory pressure when the disk alarm 
is active.

You quite possibly want to increase the default disk limit on production 
boxes, or monitor disk space externally to RabbitMQ.

Cheers, Simon
