I managed to download the Kubuntu 7.04 DVD after many hours and I am happy to leave it online for a few weeks to speed up the download for others.
After many hours with a very small upload speed ~10KB/s it occasionally starts to redownload a single chunk again.
Is there a reason why?
Does this indicate I have a corrupt download?
The Chunks tab shows 4404 total and downloaded and 0 excluded

As I watch, the seeders changes from 0(86) to 1(86) then back to (86) every now and again. Why? Is there a way for me to stop downloading and presumably stop downloading requests to make less traffic and help others?

What do the scores mean. They range from 1.73 to -1.00 plus a few -10.00 and -50.00?

What if you do a data integrity check ?

I stopped the torrent and ran the data integrity tool. It said 4 out of 4404 where incorrect.
I restarted the torrent and hours later they finished (download speed about 0.1KB/s but with about 10 peers).
I stopped the torrent again and checked to find 4 out of 4404 where incorrect.
One was in the same four as the first time, but the other three where not the same and had previously passed.

Do you have the latest version ?

I'm not intending to hijack this thread, but I think I may be getting the same issues as yopyboy.

I have a large file that I've been trying to download for a while. As soon as the download was complete, I ran an integrity check: 87 chunks failed/incomplete.

I then let the torrent complete downloading again. After it was 100% finished, I ran an integrity check again, and this time it was 78 chunks that failed or were incomplete.

I then let it finish downloading again (for the third time), and then ran an integrity check for the third time, and this time it was 86 chunks that failed.

So, 87 failed chunks -> 78 failed chunks -> failed 86 chunks. This makes no sense to me? Like I said, seems very similar to yopyboy's situation (i.e. where ktorrent appears to be finding failures on chunks that were previously downloaded and passed integrity checks), but I could be wrong.

I'm currently running Ktorrent 2.1.3 in KDE 3.5.4 on slackware 11.0, linux kernal 2.4.33.3.

Have you tried 2.1.4 already ?

Do you have a DMZ host set on any router that you're behind? I've had problems mixing DMZ and torrents in the past.
