dbus high cpu %

htop is showing that dbus (exact command in linked screenshot) is constantly using about 20% of my cpu while system is idle.  any idea why something would be triggering dbus to behave like this?  and most importantly, how may I prevent this?

Thanks.

Re: dbus high cpu %

Instead of a screenshot, you can run 'ps':

$ ps -C dbus-daemon -o args=
/usr/bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation
/usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session
/usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session

No idea why this happens, reboot and see if it went away.

Always comes back after reboot.

Yes, but does it still use 20% cpu?

Yes, it's not immediately after reboot, but within the next day or so it will be back to 20%. 

Seems to not be an issue anymore after switching from kde4 to cinnamon.  Load avg is about half what it was previously now.
