Since upgrading to Fedora 12, I've noticed a memory leak in gnome-settings-daemon. It appears that when I change the background image with gconftool-2 (/desktop/gnome/background/picture_filename), gnome-settings-daemon never frees the old image. If I stay logged in for a few weeks, I've seen gnome-settings-daemon using over 6 GB of resident memory. The currently installed version of gnome-settings-daemon is gnome-settings-daemon-2.28.1-10.fc12.x86_64. Is there any other information that would be helpful?
I haven't heard back anything about this, so I'm wondering if there is any useful information that I can provide to help. It's a pretty serious memory leak, and it's easy to reproduce. I can make it use a few gigabytes of memory in one minute just by changing the background image frequenty in gconftool-2.
I'm reassigning this to gnome-desktop because I think that this memory leak might have been introduced by the per-monitor-background patch that also caused bug #556369.
I applied spanned-background.patch (attached to bug #556369) and set /desktop/gnome/background/picture_options to "spanned". When I change the background image, there is no longer a memory leak. This convinces me that per-monitor-background.patch is the source of the memory leak.
I am also seeing this memory leak, and I this is my gnome-settings-daemon: gnome-settings-daemon-2.28.2-1.fc12.x86_64 The leak does not appear to show up when I use the 'span' style option. With any other style option for the background, when I change the background image the memory for the old image is not released.
This appears to have been fixed in Fedora 13.
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
