For other souls facing this "Medium" issue, a hammer-ish workaround that works for me:
1) Run: apt-get install cpulimit 2) edit /lib/systemd/system/systemd-resolved.service: 2a) Comment out: #Type=notify 2b) Replace line (may want to remove the -k to let cpulimit throttle it): #ExecStart=!!/lib/systemd/systemd-resolved ExecStart=!!/usr/bin/cpulimit -f -q -k -l 50 -- /lib/systemd/systemd-resolved 3) Run: systemctl daemon-reload systemctl restart systemd-resolved -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1670959 Title: systemd-resolved using 100% CPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1670959/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
