This option sets the maximum number of heap memory bytes that the broker
will allocate, and hence sets a hard limit on memory use by the broker.
Memory requests that exceed this value will be denied. The effect will
vary depending on what has been denied. If an incoming message is being
processed, then the message will be dropped and the publishing client
will be disconnected. If an outgoing message is being sent, then the
individual message will be dropped and the receiving client will be
disconnected. Defaults to no limit.</para>
