Plex Media Scanner constantly using 100% cpu

Plex Media Server Desktops & Laptops
1

Hello

Running the latest Plex on macOS Sierra. (Although I’ve had this problem with previous OSes as well).

Whenever the media server is open, the scanner constantly uses 100% of the CPU. I am able to add new media without issues, so it doesn’t seem to be frozen.

I suspect I may have one or two files that are corrupt or making it get stuck? Anyway, my library isn’t that big — about 50-60 media files.

My scanner logs are here: https://dl.dropboxusercontent.com/u/353640/media%20scanner%20logs.zip

Any help appreciated. Thanks

Try Unchecking thumbnails in Server/ library settings and restart PMS.

This worked for me - thank you. But what if I want thumbnail previews?

  1. Schedule a time in PMS that won’t interfere with your everyday computer usage
  2. Reduce scheduled tasks till thumbnails are applied
  3. Buy a more expensive and powerful server
  4. Reduce size of your Library and add a bit by bit till complete
  5. Reduce your computers opens apps
  6. Possibly buy more Ram.
  7. Try after a fresh restart at a scheduled time.

Use Emby. I never have that issue with Emby.

PMS is schedule to run daily for me, and it seems to run hourly. No matter what I do, I can’t get it to stop taking 100% of one of my cores, and run for 7+ hours. I kind of just want it to never run again, or only when I add media, but it’s not chaining that frequently to warrant this kind of activity. I have to force quit it because it’s obnoxious and hogging resources for no reason. Any advice on how to get it to stop?
