Bug ID: 443401
Summary: 300 processes of drkonqi-coredump-processor occupying
100% of CPU, Plasma desktop unusable.
Product: drkonqi
Version: master
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: david.hu...@mailbox.org
CC: david.hu...@mailbox.org, fa...@kde.org,

Target Milestone: ---
Created attachment 142209

htop showing drkonqi-coredump-processor processes.
SUMMARY
Since the last updates today, I am not able to use my KDE Neon developer
edition machine anymore, because many drkonqi-coredump-processor processes make
it totally unresponsive after a few seconds.
These processes appear at a rate of 1Hz.
At the same time, I observe a similar amount of sddm-greeter processes
appearing, each doing nothing.
When I log out fast enough, I can see one additional sddm-greeter process,
which is operational and does the login screen. The drkonqi-coredump-processor
processes continue to run, until they disappear after 300 seconds.
STEPS TO REPRODUCE
1. Log in graphically on KDE Neon developer edition, with a local X session
OBSERVED RESULT
Every second a process appears and runs at full CPU load:
`drkonqi-coredump-processor <long constant hex> <integer, counting up>`
EXPECTED RESULT
No such processes appear.
In case sddm-greeter (or something else) actually crashes and causes these
processes to appear, they should not lock up at 100% CPU.
