I've been noticing this issue for a little while. Basically ktorrent fails to announce or scrape for the first interval, so many many torrents wont even start for a half hour. And even when I do manually announce, and "update trackers" it takes a long time for anything to start happening. And this mostly just happens off of tvtorrents.

I'm using ktorrent 3.3rc1 (svn r1041897).

What does it say in the log ?

You're in luck, ktorrent crashed again. So I've had to restart it and can see the announce issue, again.

It won't let me copy from the log widget... I'm attaching the log as its already over 4k. Or not, I guess you should remove the file upload widget if its "not allowed".

Here's the entire log as it was a few seconds ago: http://strangesoft.net/ktorrent.log.nov.6.09

At this points no torrents have started downloading, and all of them show no seeds or peers.

Looking at these errors:

I know the piratebay tracker has been down for some time now, don't know about the others.

So unless your router is **** out because it's NAT table is full, because of the number of connections (you seem to have a lot of torrents), this seems to be a problem of trackers being down.

You'll notice I'm actually having problems with tvtorrents. Other torrents download fine, even ones that come from mininova (though they download slow, because half the trackers are down, but thats normal).

The tvtorrents trackers are up, and don't error out, but ktorrent won't seeminly even attempt to connect to them on start. I just went and checked and ktorrent had crashed again (md5 error?), so I started it up and it had a file loaded, but it listed no seeds, no peers and somehow it thinks the tracker is fine (OK), even though its obviously not even tried to connect to it.

If it helps, heres a screenshot I just took, a few minutes after starting ktorrent.

Are you using KIO for announcing ? (Advanced settings -> Do not use KIO for tracker announces)

Nope KIO is usually disabled because some trackers have issues with it (lovely buggy trackers!).

I'll try enabling it and see how it goes.

There also seems to be an issue with ktorrent not telling the tracker its stopped a torrent? Even after I stopped a bunch, tvtorrents said I had too many going.

Also, I've now tried using kio, it seems it reported the "you have too many torrents open" error from tvtorrents, while the other mode did not. It would probably be a good idea to make sure the error shows up when using either method.
