I use guacamole to RDP to a windows box and monitor a camera in my home. When I have the audio from the camera turned off, guacamole uses very little memory. However, when I turn on audio, guacd is leaking memory very badly. I monitor process memory usage with telegraf and grafana, and attached is the grafana plot showing the guacd memory usage over two days. I only connect to guacamole when I'm at work, and you can easily see when I connect to guacamole when I arrive and when I disconnect before I leave.
