Description Ömer Fadıl USTA 2020-09-21 05:33:05 UTC 
SUMMARY
When ksysguard launched it is about 20mb ram usage but after a while ( within half hour) it became 400mb usage


STEPS TO REPRODUCE
1. run ksysguard
2. wait about half hour
3. (if you want to see faster result just open some cpu intensive applications or do some travel around hard drive with dolphin )
 

OBSERVED RESULT
It reaches ~ 400 mb ram usage

EXPECTED RESULT
It must be around 20 - 30 mb usage

Still a problem in 5.20.0
Also a problem for the systemmonitor (System Activity) spawned from Ctrl+Esc

Leaving them both open overnight can lead to over 1 GiB of usage.
Current usage after leaving it on overnight:
ksysguard: 1.9 G
systemmonitor: 1.4 G

Same story for me:


Plasma 5.20.1
Frameworks 5.75.0
Qt 5.15.1

Memory used by KSysGuard will steadily increase and can reach 2GiB overnight.

https://github.com/KDE/libksysguard/commit/23852597c642a5c5303bb994d4d28e20d9c863cb will not compile for me with "error: ‘Updates’ in ‘class KSysGuard::Process’ does not name a type" - like errors



https://github.com/KDE/libksysguard/commit/40cb8d6acbb12e516c1d327a9b2574560adcb4ec is Ok for me,later commits have KSysGuard run away with my memory
