Scanning Problems

Help & Support
#1

Hey,

Before I begin I’ll note that this is a problem I’m also having with Radarr too, which as far as I can tell is based on the same issue.

I have Sonarr and Radarr running on a Mac with Transmission, linked in with Radarr and Sonarr in a barebones fashion. Sonarr and Radarr both periodically attempt to grab 110% of the CPU on my machine, which makes the fans go mad and certainly isn’t good for its health.

I have movies downloading to /disk/torrents/Downloads, Sonarr and Radarr symlinking to /disk/torrents/Movies and /disk/torrents/TV. I also have unrelated music stored in /disk/Music. Examination of the trace logs showed that both Radarr and Sonarr are attempting to parse the thousands of tracks in this Music folder.

A supporter from the Radarr Discord suggested that the programs were attempting to scan all the files in my torrent client, even though I had not pointed them at the Music folder, and I confirmed this given that all the CPU usage goes away when I disable Transmission in Sonarr settings.

My question is - do you have any suggestions for how I might continue to use Transmission, both for Sonarr and Radarr and for unrelated downloads, but prevent them from scanning every single download in it and causing massive lag? Thanks :slight_smile:

Set up categories.
Sonarr > Settings > Download Client > Transmission > set the Category to e.g. sonarr.
From now on, sonarr will only look at torrents in Transmission with that category (which, by the way, translates to a subdirectory of the download location for transmission).
You’ll have to change any current downloads in transmission to use this location for sonarr to see them.

Repeat for Radarr, with a radarr category.

I did so, and it didn’t create any folder with that name (that I could find, I checked) and continued to pump my CPU. I’ve already got partitioning of torrents set up in Transmission itself (e.g. torrents from MovieTrackerA go to /disk/Cinema/downloads/MovieTrackerA, torrents from MovieTrackerB go to /disk/Cinema/downloads/MovieTrackerB, torrents from MusicTracker go to /disk/Cinema/music). Does it matter where I set the main “default” Transmission download location? No torrents actually use this location, but since movies/TV all download into subfolders of /disk/Cinema/downloads, I have to somehow set it to only scan this folder? Thanks for all your help
