I have the same cpu problem. The reason for 100% cpu for me seems to start when I try to open the info page of a movie from any client(web, android, androidtv) where the movie are located at the root of the library folder, and not in a separate folder. The animated spinner appears, the server cpu goes up to 100% and nothing more happens.
The server logs say nothing.
I have to restart the emby server process for it to go away. I moved my movies that are located in the root folder to separate folders, named as the movie, and then everything works again.
The server log just contains gets and responses from me clicking around.
No new plugins installed before the problems appeared.
