- After adding more than about 4 torrents in succession, KTorrent crashes

- If added 1 or 2 torrents, then try to remove some downloads which are stopped after seeding, KTorrent crashes

Can I debug somehow, useful backtrace or something?

edit:

It seems that if when added, the torrents are queued instead of starting right away, however many torrents can be added and the program doesn't crash. The problem seems to lie with rapid succession of starting downloads.

edit 2:

Actually it still crashes, it just takes longer, ah!

A backtrace would be usefull.

Seems to be a crash somewhere in dbus, maybe you could try unloading the zeroconf plugin.

Yep, looks like it was the zeroconf plugin. Oh well, not that many ktorrent users on my network anyway =/

I have the same problem, but I cannot get a backtrace and under plugins I dont have a zeroconf plugin listed.

I am using Ktorrent 2.1.3 on Slax 6 rc2

Thanks

Mike

I have found a temp fix (for my system anyways)

I changed the webui session TTL = 1200 (from 1600)

I also configured the client machine that is loading the torrents. This machine is running Firefox 2.0.0.3. I set the cookies to expire for Ktorrent after every session.

I was able to upload several torrents without a crash. Perhaps is just a question of tweaking?

Hope this helps someone else

Mike
