Why does BitTorrent Mainline get stuck at a certain percentage for a torrent job?
Check the availability of the torrent job, the number of seeds there are in the swarm, the the number of peers there are in the swarm, and the amount of wasted data that you’ve downloaded. • If the availaiblity is below 1.0 and the number of seeds is high, then the torrent swarm is most likely fake, and was created by anti-P2P organizations. • If the availability is below 1.0 and the number of seeds is low as well, then you will have to be patient, as the torrent contents may simply not be well distributed. • If you are seeing a large amount of wasted data, check this FAQ.
