Timothy Krause (tmkrs4482) wrote : Excessive CPU usage every 9 seconds

After the system has been running for several hours the CPU usage spikes approximately every 9 seconds. I ran 'top' and noticed that systemd and dbus were using the CPU. I then ran 'dbus-monitor --system' and saw a large stream of messages corresponding to the CPU consumption. I've attached the output of 'dbus-monitor' with the bug report.
