If an MQTT client sends messages to an address and that address never has any queue created on it then it will not be automatically deleted by default since the broker will not consider that address to be "used." That may be what is happening in your MQTT "case A." If so, check out the auto-delete-addresses-skip-usage-check [1] address setting.
I'm not sure what you mean by "no memory eating" and "memory eating" in this context. Every AddressInfo object consumes memory simply due to its existence. As far as I can tell, you're deleting the address in the proper way. However, you said that it, "...looks like there are addresses related objects not removed from the broker memory..." and it's not clear what those "related objects" are. Can you elaborate on this?
