Which process is leaking? did you run valgrind to get information? Created attachment 136443 [details]
valgrind --leak-check=full --show-leak-kinds=all -s kontact
Please note that I have not used Valgrind before, so I'm mostly just going by the suggestions made by the program itself as far as flags used. Please let me know if you need more or different information.
This issue is likely caused by an downstream issue in Gentoo's qtwebengine package (see here: https://bugs.gentoo.org/773919 ). Can you try taking the steps outlined in this comment: https://bugs.gentoo.org/773919#c21 and see if that resolves your problem? Yes, that fixed the problem. Thank you for the help. |
SUMMARY The entire KDE PIM GUI application suite leaks memory and CPU time as it is running. STEPS TO REPRODUCE 1. Start any Kontact process (kontact, kmail, akregator...) OBSERVED RESULT The process will start running at 100% or more CPU time. Memory usage will also increase by up to ~35 MB per second. These are observable through the top terminal tool. Running the application in terminal will also output this message continuously: [671057:671057:0225/{timestamp}:ERROR:network_service_instance_impl.cc(286)] Network service crashed, restarting service. Closing the application when it was run in terminal will also output this message (multiple times for kontact): kf.xmlgui: 0x5641a2dc9ad8 deleted without having been removed from the factory first. This will leak standalone popupmenus and could lead to crashes. EXPECTED RESULT The program runs normally and does not leak CPU time or RAM.
