[jira] [Created] (KAFKA-9702) Suspected memory leak

Nishant Ranjan created KAFKA-9702:
-------------------------------------

             Summary: Suspected memory leak
                 Key: KAFKA-9702
                 URL: https://issues.apache.org/jira/browse/KAFKA-9702
             Project: Kafka
          Issue Type: Bug
          Components: consumer
    Affects Versions: 2.4.0
            Reporter: Nishant Ranjan


I am using Kafka consumer to fetch objects from Kafka topic and then persist them in DB.

When I ran, eclipse MAT for memory leaks, its giving following :
53 instances of *"java.util.zip.ZipFile$Source"*, loaded by *"<system class loader>"* occupy *22,33,048 (31.01%)* bytes.

Also, my observation is that GC is not collecting objects.

Please let me know if more information is required.
