Description:
we have seen IoT Agent not receiving all the data from MQTT Broker(Vernemq) after restart the MQTT broker.Plz find below the testing scenario.
we did the testing with MQTT Broker(vernemq) in 1 ec2 and 2 iot Agent with restating vernemq in between
1- send 11 and 24 records
Received 11 and 24 at iot agent
2- Restarted EC2 vernemq
3- send 24 records
Received 7 at IoT Agent
Note: Where other Subscriber got all 24 records at same time.
