Error description
The KafkaConsumer and KafkaProducer nodes will leak a small amount of Java heap memory if they fail to establish a connection to the Kafka broker. This can accumulate over time and become noticeable if frequent connection errors are experienced by the message flow. The root cause of this issue is that the Kafka nodes do not correctly clean up all Kafka connection resources before discarding a failed connection.
