OH3 [nding.zigbee.serial.ZigBeeSerialPort] - Processing DATA_AVAILABLE event: Serial buffer overrun

Got a few hundred of these messages twice today … doesn’t seem to have any effect and I have no idea what I might have been doing at the time to have caused it … just thought I’d log this event.

I’m using the Ember EM35x Coordinator on a Pi4 running openhabian with openHAB 3.2.0Build #2469.

I dropped back to openHAB 3.2.0.M2 (for other reasons) and I am still seeing the same flurry of Serial buffer messages.
