Bug ID: 475461
Summary: Background parser requires huge amount of ram on big
projects e.g. the linux kernel
Classification: Applications
Product: kdevelop
Version: 5.12.230801
Platform: Flatpak
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: w...@tuxedocomputers.com
Target Milestone: ---
SUMMARY
Working on the linux kernel with kdevelop had it crash on me consistently when
the background parser reached ~30%. Looking into the system monitor I saw that
when opening the linux kernel source in kdevelop, the ram usage continiously
rises and the crash happens when I'm out of ram and swap space. For testing
purposes I increased my swap to 172 GB. Now it no longer crashes, but ram+swap
usage is between 80 and 100 GB
STEPS TO REPRODUCE
1. Open the linux kernel source with kdevelop
OBSERVED RESULT
KDevelop uses huge amount of ram and eventually crashes
EXPECTED RESULT
More reasonable ram usage
SOFTWARE/OS VERSIONS
Linux Kernel Version: 6.2.0-10025-tuxedo
KDE Plasma Version: 5.27.8
KDE Frameworks Version: 5.110.0
