Description Volker Hemmann 2008-07-06 12:33:23 UTC
Version:            (using KDE 4.0.83)
Installed from:    Gentoo Packages
Compiler:          gcc 4.3.1 
OS:                Linux

When opening that site in a tab or window the 'konquror' process will use more and more memory while the side is stuck at '55%' and nothing shown.

I have 4GB of ram and 4GB of swap - and with several gb of ram (ps aux says 75-80% in the MEM column) the system is badly affected. I usually kill konqueror at that point.

ps aux looks like this:

and after killing all kio_http:

the D is probably because of the heavy swapping at that point.

Looks like this is split 50/50 between kio & konq on cpu as seen by top.

Gdb gives something some of which might be useful:

ADMIN: Please upgrade severity to critical. Not only is this bug a severe memory leak, the behavior can be classed as a denial-of-service attack. The fact that this is occurring with a mainstream site (Houston Chronicle) is particularly bad.

I encountered this bug with an SVN trunk build as of 2008-08-24, on an x86-64 Debian/etch system. It is consistently reproducible. My URL: http://www.chron.com/disp/story.mpl/headline/metro/5962590.html
