Hello @Alexandru Gavrila, welcome to this moderated Azure community forum. I tried to figure out what is happening but the logfile is quite large... Which protocol are you using?
...that takes input from an IoT Hub
You mean you are listening to incoming messages from the IoT Hub using the 'eventhub compatible endpoint'?
If so, you you use a custom consumergroup, created in the IoT Hub portal:
Each consumer should use its own consumer group so each cosnumer gets its own copy. Otherwise, the stream becomes unstable. The effect you see looks like this issue... Otherwise, are you using some SDK to connect to the IoT Hub (eventhub compatible endpoint)? Which?
