> When the client sends a produce request in an abnormal way and the server accepts it for deserialization, a "java.lang.IllegalArgumentException" may occur, which will cause a large number of "TopicProduceData" objects to be instantiated without being cleaned up. In the end, the entire service of kafka is OOM.
