hudeqi updated KAFKA-15397:
---------------------------
Description: 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.
> Deserializing produce requests may cause memory leaks when exceptions occur
