Bug ID: 424636
Summary: System monitors leak memory, to a tune of 1GB (!) per
24 hours.
Product: plasmashell
Version: 5.19.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: System Monitor
Assignee: notm...@gmail.com
Reporter: gilb...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
Just upgrade two of my Fedora KDE boxes to 5.19.x and I'm noticing huge memory
leak from plasmashell.
I'm putting the blame on the system monitors, as removing them all seems to
solve the problem.
I literally have to reset plasmashell (kquitapp plsamshell && plasmashell &) as
it eats ~30GB of RAM. (Both machine have 32GB RAM).
Reverting back to 5.18 solves the problem.
