I'm trying to understand memory usage in rabbitmq. Pointers to relevant
docs, salient comments etc greatly welcomed. We have a number of batch jobs
that are handled by one process putting information on a queue and then
storm spouts read the info off and process. In the case of one job, we put
about 5.9 million integers on a queue as individual messages and process.
When those 5.9 go on, rabbitmq usage jumps up by about a gig.

Currently with 5.6 million still in the queue, we have the following memory
usage on the node as determind by rabbitmqctl status:


Can anyone shed light on the high level of memory usage and what we could
do to cut down on it?
