ZigBee Converter Temperature Warning

I have one OH running 4.3.5 with the ZigBee binding. Recently I started getting warnings such as the one below. Any thoughts? I’m restarting OH to see if that helps. No other related info in the log file - it just started a few days ago and continues on every 10 minutes or so.

Restarting OH did not help - still getting the warnings.
