> After upgrade from kafka 2.1.1 to 2.4.0, I'm experiencing unexpected consumer offset resets.

> All resets are perfectly correlated to rolling new segments at the broker - segment is rolled first, then, couple of ms later, reset on the consumer occurs. Attached is grafana graph with consumer lag per partition. All sudden spikes in lag are offset resets due to this bug.
