Server Version#: 1.40.5.8854
Player Version#: 4.136.0 (Plex Web)
Using the Scan my library periodically setting causes RAM use to slowly rise in what I assume is a memory leak. Turning this setting off and restarting Plex fixes the issue. Setting the time intervals to higher amounts seems to slow the constant rise of memory usage, but the actual problem of a (possible?) memory leak persists.
