I looked into those dbus messages and didn't find anything helpful. My system is fully up to date and I still have this issue.
Here's my current workaround: sudo sh -c 'echo "#!/bin/bash /usr/bin/killall /usr/lib/policykit-1/polkitd" > /etc/cron.daily/kill-polkitd' sudo chmod +x /etc/cron.daily/kill-polkitd -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1470235 Title: PolicyKit high memory usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/policykit-1/+bug/1470235/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
