> We are attempting an upgrade from Kafka 2.0 to 2.3 on a single cluster setup. We have a mixture of Java/C++ and Python clients (Python clients are using kafka-python libraries).
> After the upgrade, the log cleaner occasionally dies with the attached stack trace. Using timestamp correlation, we pinned it down to the cleaning of a __consumer_offsets partition. The config logged at initialization shows that
> inter.broker.protocol.version = 2.3-IV1
> log.message.format.version = 2.3-IV1
> We initially thought this was to do with unclean upgrade from 2.0 to 2.3, but after resetting the consumer offsets topic (via [https://medium.com/@nblaye/reset-consumer-offsets-topic-in-kafka-with-zookeeper-5910213284a2]) this still recurs on initially empty consumer offset partitions.
> At the moment we are working around by toggling log.cleaner.threads option using dynamic broker configuration to restore the log cleaner threads
