I have Fedora 35 with the latest updates of KDE. I have 10s of TBs of storage attached to my system, both by internal and external HDDs. So Baloo indexing service would end up taking above 30 GB of RAM. I have tried to disable Baloo but I think I didn't do it probably. My system crashes about twice or thrice every week. Everything stops working. Only a reboot solves it.
The journalctl messages shows a Baloo error, and it just continues forever.

FWIW, pasting text files as actual text would have been easier than screenshots...

Anyway, try to run this:

Code: Select all

balooctl suspend
balooctl disable

This should stop and disable Baloo on the next reboot (you need to reboot for the disable to take effect).
If you want to erase the index, run

Code: Select all

balooctl purge
