@bastiaan_van_h nice to hear you find the binding useful! 
I haven’t seen these issues myself with the binding so most likely something else is making your OH unresponsive.
There is another topic where people report heavy CPU usage including the “Thread starvation or clock leap detected” logging: Openhab2 java cpu 100% . I’ve added some replies to that topic on how to find in OH the threads that are using the most CPU time.
