Plex Media Server.exe Constantly Uses 11 - 15% CPU @ Idle

Server Version#: 1.14.1.5487
Player Version#: Varies / Web: 3.77.4

Hey Guys -

I use my primary workstation for many things including running Plex Media Server on Windows 10 x64. Recently, I’ve noticed that despite nothing playing, no scanning active, and no other tasks running, "Plex Media Server.exe is constantly using 11 - 15% CPU - like 24/7 - even after restarting app and reboots. I’ve verified that maintenance tasks are scheduled for nighttime and that all optional tasks seem to be disabled. Yes, I know it doesn’t sound like a lot, but for me it’s a big chunk.

Below are system specs, some configurations, library stats, and log snippets. If you don’t see anything that stands out, any suggestions for what the cause may be?

Note: I’m planning to move PMS to a Docker container on a dedicated system soon, but cannot figure out how to mount and use Windows Shares to work with a container on an Atomic (Fedora 28) host.
