Nishant Ranjan commented on KAFKA-9702: --------------------------------------- When I execute proper code on linux server with approx 500,000/600,000 then memory shoots to 6GB and then I gets OOM (memory constraints). Above was sample from laptop on windows (kind-off "Hello World" of problem). To identify the memory issue, I just wrote 3 lines : while(true) { consumerRecords = consumer.poll(1000) ; consumerRecords = null; } Even with above MAT is showing probable leak. Maybe, I am missing some Kafka option but there is some memory issue. > 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 > Priority: Major > > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
