Bug ID: 440559
Summary: Certain parts of KDE Plasma stop working after
long-term use
Product: plasmashell
Version: 5.22.4
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: alerikaisatt...@protonmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
This is a highly enigmatic bug. After long-term use of KDE Plasma (for a few
days without restart) one or more of the following stop working:
* Thumbnails for new images/videos in Dolphin
* Starting software via keyboard shortcuts. This may affect Dolphin, Spectacle,
Krunner, but never Konsole
* Opening any files via Dolphin
* Certain actions in Dolphin (for instance, change ownership)
Prior to Plasma 5.22, every failed action was accompanied by log message
This application failed to start because no Qt platform plugin could be
initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl,
offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl,
wayland-xcomposite-glx, xcb.
from either kdeinit5, kglobalaccel or, in case of opening a file in a program,
that program. This message was followed by a crash message.
In Plasma 5.22, however, the message is
QProcessPrivate::createPipe: Cannot create pipe 0x55848c032c68 (Too many open
files)
with the number different every time. No crash messages
STEPS TO REPRODUCE
This bug is quite hard to reproduce, exact trigger is not known
1. Use Plasma for multiple days with no restart
2. After some time, some parts of Plasma (described above) stop working
OBSERVED RESULT
Using Plasma for multiple days causes some functions to stop working
EXPECTED RESULT
Using Plasma for multiple days must not cause any problems
SOFTWARE/OS VERSIONS
KDE Plasma Version: Present at least since 5.19 to 5.22. Possibly was present
before 5.19 as well
