Comment 1 Ivan Vasic 2006-11-20 22:22:10 UTC

It was caused by setting paused state with bandwidth scheduler, probably not because there were too many torrents. I'll see what I can do about this.

In the meantime you could try playing with bandwidth scheduler (setting paused state a few times) and see if it crashes everytime.

Comment 2 yanosm 2006-12-15 03:51:27 UTC

This happens to me with only one torrent, but with that one torrent having many, many files and folders as I try to select only a few files from that list. Usually I'll be half way done unselecting whole folders when it will lock up for a few moments, then crash.

After this happens to me KTorrent will immediately crash every time I attempt to reopen it. The only way I have found to get it running again is to manually delete the torrent folder (tor#) in ~/.kde/share/apps/ktorrent or whatever you have selected as the "Folder to store temporary files." After deleting that folder, it starts right back up with no problems.
