Bug ID: 496616
Summary: Memory leak in FstabHandling for krunner, kded6,
plasmashell, kde-powerdevil and ksystemstats
Classification: I don't know
Product: kde
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: 677ee...@duck.com
Target Milestone: ---
Created attachment 176067
--> https://bugs.kde.org/attachment.cgi?id=176067&action=edit
archive of heaptrack memory logs for components. Each file can be extracted and
analyzed with heaptrack-gui
SUMMARY
Memory usage of mentioned processes increase linearly, at identical rates,
reaching a roof of 4GiB after 4-5 hours. On my system, this leads to OOM, and
me having to manually kill e.g. krunner.
STEPS TO REPRODUCE
1. Boot the system
2. Observe the gradually increased memory usage
3. Analyze the processes with `heaptrack`
OBSERVED RESULT
Some KDE components leak memory. A common trait among the processes analyzed,
shows that the function `__GI__strdup` in `libc.so.6` of `fstabHandling` of
`libKFSolid.6.so` ; is responsible for 99% of the memory usage.
EXPECTED RESULT
Stable memory usage of KDE components when not being used.
