Stalled Downloads when using Multiple Torrents

[das329717]

I have a strange problem. Not sure if this is related to ruTorrent or my .rtorrentrc. I experience the following behavior:

• No torrents in rTorrent.
• Add torrent #1. Torrent #1 begins downloading as fast as possible. Priority defaulted to normal.
• While #1 is downloading, I add and start torrent #2. Priority unchanged from the default, normal.
• Because torrent #1 is completely saturating my download bandwidth, torrent #2 gets very little (< 5 kB/s) or no download bandwidth.
• Torrent #1 eventually completes, but torrent #2 never takes off. It will just idle at 0-5 kB/s.
• If I stop it and start it again, it immediately picks up and downloads at normal speeds.

Similar behavior will happen when I start the rtorrent daemon with two downloading torrents in the queue. They start out fighting over the bandwidth, then one will succeed, maximize, and lock the other out.

Anyone else experienced this?

and you're sure this isn't just related to the torrent itself? If not then i can't think of a reason this should happen....i've never seen that. (not saying it's not true)

Happens on multiple trackers with multiple torrents. Public and Private. Most of my torrents are from various private trackers that are very well seeded. The restart of a stalled download results in instant increase to normal speed (as long as there are no other contending torrents). I don't think it's a seeding issue or even at network issue. This doesn't happen on my other systems on the same LAN with different clients

try setting download_rate to non zero?
