Upon closer inspection, I noticed a few coredumps in HTOP. Looking at coredumpctl -r list , it was filled with : Tue 2018-04-24 14:13:32 JST 14647 1000 1001 6 present /usr/bin/kactivitymanagerd About three per second ! pkill -f kactivitymanagerd stopped the coredumps and high cpu usage. -- You are receiving this mail because: You are watching all bug changes.
