> tl;dr: Broker memory usage not consistent after reboots
> Steps to reproduce the issue:
>  * Created a broker (Both on a personal instance as well as with AmazonMQ)
>  * Started producing messages directly to one or more destination queues without any consumers polling the queue
>  * All messages were sent to the broker with persistent mode
>  * As messages are sent to the queue, the memory % rise as seen from the ActiveMQ console. It can go all the way up to 99% after which it starts rejecting messages
>  * Once the broker is rebooted, the memory percent goes down to 0 even when the queue still has all the messages.
>  * When continuing to send additional messages, the memory percent does not go up
>  
> It almost seems like caching led to memory % rise until broker reboot. After reboot, caching of messages was not active and memory % stayed down
