Subject Re: Does a persistent message stay (keep) on the broker forever ?

Glad to hear.  Yes, the "store" limits the disk space that the broker 
will use.  Once that limit is reached, the broker will kick in "producer 
flow control", where it will not ack messages to producers.  This allows 
the consumer to "catch up" and drain the queues.

You shouldn't have to tweak things like cursors and turn off producer 
flow control in most scenarios, but if you want some nice bedtime 
reading you can get more detail here:
