@killyourfm @kde Yes the baloo is a service in KDE and its known to be not working correctly. A few years back when I researched, no one was working on this program. It's the file indexer for the KDE search functionalities. When I was using KDE, I ended up disabling and removing baloo. Not only takes it so much memory, it also used one of my 8 threads of 4 real cores to be almost always 100% working.
Just websearch for something like "baloo ram memoryleak too much" and such. It's common problem
