Kubuntu 18.04 LTS x64 Some seconds after typing any character in krunner(invoked by ALT+SPACE) or in the KDE menu search box, the hard disk is occupied heavily and the system becomes unusable, only cold reboot or shutdown by holding the power button is possible. The mouse pointer moves from time to time. The same thing happens when I am trying to search for files in Dolphin using the "Find" box.
Now baloosearch crashes all the times through dolphin. Through the konsole baloosearch occupies the hard disk for a long time like through krunner, if you wait it stops after some minutes but the system is a bit laggy. In system statistics the baloorun process occupies the whole 4GB ram. The problem comes from baloo.
