What do you mean with memory increase ? sd_bus is unlikely to have any severe memory leak under normal conditions (if there is any, they are usually found in error paths) so you are either mis-using the api or misunderstanding memory management. if there is any memory leak either in your code or in sd_bus it will be found building both your code and systemd with leak sanitizer.
