C7 hub. Latest firmware (2.2.3.145). It also happend on the last few 2.2.3.x versions. This is an unpredictable occurrence - sometimes everything is fine. Other times, there is a burst of these log messages for one physical or control action.
As a further investigation, I wrote a simple JavaScript program to monitor the eventStream port and these messages are repeated on the eventStream - so its not just a logging issue, these are events that propagate through the system. That can't be good for performance!
