Yes. All rabbit releases up to the current one require that all messages 
fit into RAM. When memory gets tight, rabbit throttles producers.

The much talked about "new persister", which is scheduled to appear in 
the next rabbit release, removes the memory constraint, allowing rabbit 
to hold as much message data as there is disk space.
