Peer connections dropped when seeding

[Kimiko]

After a torrent switches from downloading to seeding, almost no new uploads are started. I see clients connecting, then not actually downloading anything, then disconnecting. As a result, after a week I still have seed ratios <1, even though the numbers between () in the peers column are >0 most of the time.

This seems to happen more often after the daemon has been running for a while. I.e. I can sometimes get it to upload a little again by restarting the daemon. I tried running the daemon with logging enabled, but even at -L debug there's nothing about failed connections or whatever.
