Bug ID: 507670
Summary: Applications are very slow at opening/don't open after
a few hours of uptime
Classification: Plasma
Product: plasmashell
Version First 6.4.3
Reported In:
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
SUMMARY
After some hours of uptime (around 12-16 hours), applications don't open, or
open very slowly (likely after the dbus timeout is reached), and notifications
stop working. The application launcher doesn't open either.
For example, this is the journalctl output when opening Brave:
Jul 31 00:29:34 SagnikS-WS-1 systemd[3377]: Started
[email protected] - Brave - Web
Browser.
Jul 31 00:29:34 SagnikS-WS-1 systemd[3377]: Started
app-flatpak-com.brave.Browser-2277530041.scope.
Jul 31 00:29:34 SagnikS-WS-1 systemd[3377]: Started
app-flatpak-com.brave.Browser-1794326370.scope.
Jul 31 00:29:34 SagnikS-WS-1 flatpak[1679996]: Opening in existing browser
session.
Jul 31 00:29:59 SagnikS-WS-1 plasmashell[1306317]: kf.kio.gui: Failed to launch
process as service:
"[email protected]"
"org.freedesktop.DBus.Error.NoReply" "Did not receive a reply. Possible causes
include: the remote application did not send a reply, the message bus security
policy blocked the reply, the reply timeout expired, or the network connection
was broken."
And when opening spectacle:
Jul 31 00:21:10 SagnikS-WS-1 spectacle[1675319]: Error querying plasma version
"org.freedesktop.DBus.Error.NoReply" "Did not receive a reply. Possible causes
include: the remote application did not send a reply, the message bus security
policy blocked the reply, the reply timeout expired, or the network connection
was broken."
STEPS TO REPRODUCE
1. Have a long enough uptime
2. Try to launch any application
SOFTWARE/OS VERSIONS
Operating System: Fedora Linux 42
KDE Plasma Version: 6.4.3
KDE Frameworks Version: 6.16.0
Qt Version: 6.9.1
Kernel Version: 6.15.7-200.fc42.x86_64 (64-bit)

Processors: 32 × AMD Ryzen 9 5950X 16-Core Processor

ADDITIONAL INFORMATION
Running plasmashell --replace in krunner does not fix it. So far the only way I
have been able to fix this, albeit temporarily, is to kill -9 the plasmashell
process and then it restarts without any problems.
This problem started about 3 days back after I updated Fedora KDE, prior to
that there were no problems.
