Rabbit won't fail when you stuff it full of messages. It will block
producers when it runs out of ram/disk space. See

Why not? 50 producers is not a lot; each producer could happily do a
passive declare of the queue(s) every minute w/o any measurable impact
This does require producers to know what queues their messages may get
routed to, and also gets problematic when you have thousands of queues.
But it doesn't look like these concerns apply to your set up.

See the flow control mechanism above.
