Description

Configuring the broker for transport trace:|

<transportConnectorname="openwire"uri="tcp://0.0.0.0:61616?trace=true"/>
</transportConnectors>

makes the broker create a new SLF4J Logger instance for every single connection.
This Logger never get cleared not even when the connection is closed which can lead to OOM on load.

trace=true is a great diagnostic tool but cannot be left enabled on a broker long term because of this.
