hudeqi commented on KAFKA-15397:
--------------------------------

It seems that this commit: ”MINOR: Add more validation during KRPC 
deserialization“ can effectively avoid this memory overflow problem, so close 
this issue first.

> Deserializing produce requests may cause memory leaks when exceptions occur

> 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.
