Hello.
I'm using ktorrent 4.0 and I have a problem with disc overload.
After lunching ktorrent and starting seeding some torrents, hard drives go to overload state and all system starting laging horrible. It's even hard to move mouse.
And I have noticed that if I seed some file by torrent and same file is on my iroffer irc bot, iroffer start saying "WARNING: File [file seeding by ktorrent] has changed". But checksums doesn't change. Maybe files are opened with wrong permission?

I had the exact same thing you experienced. I could not select anything or use ktorrent at all. I didn't see any other reports like that so I just went back to 3.3.4.

Using Kubuntu 10.04, KDE 4.4.3 fwiw.

Which filesystem are you using ?

It's probably caused by a new mechanism to prevent crashes when running out of diskspace. There appear to be some issues with that, but haven't been able to reproduce the problem.

I'm using ext3 filesystem.

Kernel: 2.6.33 gentoo
KDE: 4.4.3

If you need some ktorrent logs or something else, just say what you need. I try to make them.

I'm also using ext3 and not seeing any of this.

Do you have "reserve diskspace before starting a torrent" enabled ? If so is full diskspace reservation enabled ?

Also do you get the same behavior when downloading a torrent ?

"reserve diskspace before starting a torrent" and "full diskspace reservation" was enabled.
I tried to disable it, but nothing change.

When a tried to download something ktorrent report:


The system filesystem are reiserfs (i mean "/", "/home/", etc). But all hard drives i using for file kipping are ext3 ("/mnt/*"). May be reason in this?

The problem is caused by ext3 not supporting a feature, and the function used to prevent crashes when you run out of diskspace, then falls back to a very slow and hard disk intensive alternative.

This should now be fixed
