SUMMARY There's a crash report visible in systemctl STEPS TO REPRODUCE 1. Nothing specific, just use the computer and at some point it crashes. 2. 3. OBSERVED RESULT System freez or crashes. The freezes and crashes might be unrelated, I can't know for sure EXPECTED RESULT No crash. SOFTWARE/OS VERSIONS Linux/KDE Plasma: ArchLinux, Plasma 5.18.1 (available in About System) KDE Plasma Version: 5.18.1 No other informations as I can't have them by the about menu: I installed several DE/WM on this computer and sometimes use one or another. The current crash report happened on a Gnome session, but it seems that Baloo service is anyway running everytime once instealled with the KDE DE, whether it's a KDE session or not. ADDITIONAL INFORMATION The system is encrypted through LUKS, which might explain heavier resource usage. Here's the stacktrace from journalctl: Feb 19 00:28:10 T470-clement systemd-coredump[46933]: Process 46873 (baloo_file) of user 1000 dumped core.
