Description of problem: "lsof -p $xServerPid" shows increase in list of "/drm mm object" lines every time a new kde application is started. e.g. # lsof -p $xServerPid 2> /dev/null | grep "/drm mm object" | wc -l 10254 $ kwrite & pid=$! ; sleep 2; kill $pid # lsof -p $xServerPid 2> /dev/null | grep "/drm mm object" | wc -l 10266 Closing the application doesn't release the resources. Opening a xterm or gedit doesn't cause any leakage. This might be a duplicate of bug 487552 and/or a kde bug. Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.6.1.901-1.fc11.x86_64 kernel-2.6.29.6-217.2.16.fc11.x86_64 xorg-x11-drv-intel-2.7.0-7.fc11.x86_64 kdebase-workspace-4.3.0-9.fc11.x86_64 How reproducible: Open a new kde application. Terminating the application doesn't release resources. Actual results: Steady increase of "drm mm object" lines in lsof output every time a new kde application is started. Expected results: Some what constant amount of "drm mm object" lines in lsof output.

Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages. For packages from updates-testing repository you can use command yum upgrade --enablerepo='*-updates-testing' Alternatively, you can also try to test whether this bug is reproducible with the upcoming Fedora 12 distribution by downloading LiveMedia of F12 Beta available at http://alt.fedoraproject.org/pub/alt/nightly-composes/ . By using that you get all the latest packages without need to install anything on your computer. For more information on using LiveMedia take a look at https://fedoraproject.org/wiki/FedoraLiveCD . Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you. If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you. [This is a bulk message for all open Fedora Rawhide Xorg-related bugs. I'm adding myself to the CC list for each bug, so I'll see any comments you make after this and do my best to make sure every issue gets proper attention.]
Drm mm objects keep leaking in F11. Tested after applying latest updates (yum upgrade --enablerepo='*-updates-testing') and reboot. Reproducing this issue is not as straight forward as before but the leak is still as aggressive as before. It usually takes few minutes while playing with the desktop something like this: 1. open konsole 2. minimize/maximize/resize window 3. move mouse cursor over task bar items and let the popup appear 4. hit alt-tab several times 5. open some other application and toggle some drop down menus 6. close the application 7. toggle konsole menus 8. goto step 1. I can observe that lsof -p $(pidof X) 2> /dev/null | grep -c "drm mm object" shows increasing amount of drm mm objects. Some times it can take few minutes to make object count increas. In a long run the X virtual memory grows big enough and the system starts to swap heavily. The problem seems to be fixed in F12 :) Tested with kde-x86_64-20091111.16.iso.
(In reply to comment #2) > The problem seems to be fixed in F12 :) Tested with kde-x86_64-20091111.16.iso. Juha, per my guidance from mcepl, since you report this issue resolved using Fedora 12, I'm going to close this bug report as CLOSED RAWHIDE. While we understand that the issue remains under Fedora 11, it was been resolved with the updated system. Thank you for your time and efforts in spotting, reporting and testing this issue. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
