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.
