Zigbee, double log entries, periodically

2.3.1.142 C7

My "sensor" is (supposed) to send a message string every 5 minutes. Looking at the logs I find periodically I will receive double messages with nearly the same time stamp. Actually some have the identical timestamp.
When the double messages occur there are usually 3 to 5 bad messages then OK for some hours.

Have others seen this? Should I look to the hub or the sensor to try and track down the issue?
Thanks
John
