Switching sources causes minor memory leaks

simple module

echo "

parameters:

    SourceBuilder()
    .with_socket('dealer+connect:ipc:///tmp/zmq-sockets/input-video.ipc')
    .with_module_health_check_url(healthcheck_url)
    .build()

Monitor memory consumption with e.g. nvtop. Each client run (1k source change) adds +10M RSS MEM for the app module.
