This indicates that rabbit got close to running out of memory and told all connected clients to stop sending any more messages. Hence the "Discarding ..." message you were seeing in the erlang client. Your consumers should continue to receive messages, albeit slowly if rabbit is swapping.<br>
<br>
Perhaps your consumers are not acknowledging received messages, causing them to keep piling up at the server?<br>
<br>
I recommend checking the queue lengths/sizes with 'rabbitmqctl list_queues'.<br>
