Bug 35092 – X uses far too much memory when using konqueror to view a large number of images

• Product: Gentoo Linux
• Status: RESOLVED UPSTREAM

[Description bdonlan 2003-12-04 14:41:39 UTC]

After viewing approximately 1500 relatively large images (averaging 635 x 1013)
in konqueror in succession, Xfree86 jumped from ~100M mapped address space to
~1G, with a corresponding increase of swap usage. Had this continued, X would
have used all my swap and caused the OOM killer to be invoked, thus (probably)
killing X, leaving the video hardware in an indeterminate state.

Killing konqueror reduced the X memory usage to sane levels. It is probable that
konqueror does not free the server memory used to store the images, but I do not
have the coding skills to fix this.

Reproducible: Always
Steps to Reproduce:
1. View a long series of images in konqueror without closing the browser.
2. Examine your imcreasing X memory usage.


Actual Results:  
X's memory usage increased by nearly a gigabyte.

Expected Results:  
X's memory usage should have remained relatively stable.

I am using vanilla kernel 2.6.0-test11, konqueror 3.1.4, and XFree86 4.3.0-r3.

Not much I can do for you here.  You're welcome to report this to the kde team at bugs.kde.org, but I don't know what their reaction will be - they probably will need more information in order to come up with a fix, if they consider it a bug.
