Been getting these messages in logs for a month or so now. Can't figure out what is causing it. I have been noticing problems with Z-Wave devices not responding to commands as well, so I think the two issues must be related.
Also, is there a trigger I can use in RM to get a notification message every time this happens?
Have you done a shut down and power cycle? That should at least clear it up for a while, or forever. Sometimes the radio just gets all balled up and need to be restarted with a shut down. If it comes back pretty quick then you must have a misbehaving device.
I don't think there is a way to trigger that in RM unless you setup a log listener to the websocket.
