This is an old issue and basically Plex Media Server does not work correctly if its back-to-back tcp connections for the python system process are killed and when that happens it ends up in a loop.
This was registered as an issue at the time it was discovered but there are NO plans to make any changes to Plex for this - Plex does need its connections running and not tampered with by any other third party product
These are the original investigations into the issue
