Since some time I have been experiencing gradual RAM consumption increase by SickBeard, Plex and Radarr - it used to be that I had about 50 % of RAM used all the time, but within the week it got up to 70 % on "idle" (of course server is doing some scheduled tasks, but the number is an average from few hours). Below you can see results of htop.
Is it ok that there are so many processes?
