It has been a long time since I used stremio, but IIRC it used to have a max cache size for torrent plugins. The default setting was something like 10GB, which means older torrents eventually get deleted after you stream a certain amount of other content.
I suspect stremio seeds torrents in the cache directory, so if you increase cache size, you can potentially continue seeding torrents for more time after the initial download.
