Hmn, I can't get that to break, because I can't get the queue to be non-empty in the first place. Here's what I'm doing, perhaps you can point out the step I'm missing.

1. start the broker
2. start the producer
3. start the consumer
4. set the watermark very low using rabbitmqctl, e.g., 0.001
5. see the alarm in the logs
6. stop the producer

** at this point, the queue is always empty

7. stop the consumer
8. start the consumer

** but at this point, the exercise is moot, because the queue is empty so 'blocking' is the expected state. Sorry I didn't check on this with you sooner - I didn't realise I needed to look at that when I got started as I wasn't clear on the implication of "blocking" as the consumer state. The consumer stays in this state of course, since there are no messages in the queue.

So what am I doing wrong here?

Cheers,
Tim
