Quick remark: I think we are talking about different examples here. It looks like the example you are referring too is a FastRTPS example, that uses different QoS settings (amongst other things) that the ROS2 talker / listener example that @wjwwood is referring too. @NotMe do you have the same behavior with the ROS2 talker / listener examples? --- [Visit Topic](https://discourse.ros.org/t/fast-rtps-memory-usage-please-help/1739/3) or reply to this email to respond.
