Bug ID: 505652
Summary: repetitive crashes of kwin_x11 and plasma over time
(it seems that certain ressources are not available)
Classification: Plasma
Product: plasmashell
Version First 5.27.11
Reported In:
Platform: openSUSE
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: developm...@diargo.de
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
Application: plasmashell (5.27.11)
Qt Version: 5.15.12
Frameworks Version: 5.115.0
Operating System: Linux 6.4.0-150600.23.50-default x86_64
Windowing System: X11
Distribution: "openSUSE Leap 15.6"
DrKonqi: 5.27.11 [KCrashBackend]
-- Information about the crash:
These kind of crashes appear regularly after a while and can be handled by
killing the process of kwin_x11 (sudo kill -9 <>) or restarting kde plasma. It
seems that certain ressouces (memory for GUI) are used up maybe by rogue
prcoesses.
I think it is important to supply a utility (a health check) with which the
user can easily query the available memory of KDE oder kwin_x11 and to report
which process ist using what amount of these ressources.
kind regards
F. Gotsis from Munich, Germany
The reporter is unsure if this crash is reproducible.
