We have single node deployed in docker and consumer services are written in dotnet core with c#.
We are facing issue when sometimes old message are consuming automatically by consumer without any changes in consumer group.
Are you able to repro this? It’ll be easier to figure this out if you can trigger it rather than observe from time to time.
Any interesting logging client or server side (if you have access) when this happens?
How are you managing / committing consumer offsets?
No, it’s random and not able to repro the same !
