> We observed another instance of the problem reported in KAFKA-2300, but this
> time the error appeared in the partition state machine. In KAFKA-2300, we
> haven't cleaned up the state in {{PartitionStateMachine}} and
> {{ReplicaStateMachine}} as we do in {{KafkaController}}.
> Here is the stack trace:
