kio_file uses masses of memory after some time running

[IanBall]

Binary package hint: ktorrent

After a few hours, ktorrent and it's kio_file slaves use masses of memory. I have Ubuntu 9.10 on an AMD64 system, 4Gb ram. this renders the system extremely slow as almost everything is swapped out. Quitting from ktorrent frees the memory. Simply minimising or leaving it in the system tray does not help. I am sharing two 1.5Gb files.

From top sorting by memory usage:

As you can see, the system is totally bogged down in wait states while it waits for hard drive i/o.

Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. While we appreciate your issue, it would be better if it was tracked at https://bugs.kde.org, so that the KDE developers can deal with this speedily and have direct communication with you as the reporter for more effective debugging.

Thanks!

I have created a new bug, because I'm not sure the the link at #3 is the same.
