> When memory of the broker reaches its limit, the store-based cursor will page messages to temporary files or store them to a database ,thus the producer can send messages again. But if we set the destination policy with a low limit of memory, the producer will be hung because the store-based cursor will do nothing. 
> I have attached a junit test case to show these diverse results.
