Manikumar Reddy commented on KAFKA-936:
---------------------------------------
After KAFKA-1481, I am observing one issue. We are not removing the newly
added Version/AppInfo Mbean on old producer/consumer close call. There is no
other memory leak. Will submit a patch for this.

> I am using kafka_2.8.0-0.8.0-SNAPSHOT version. I am running into
> OutOfMemoryError in PermGen Space. I have set the -XX:MaxPermSize=512m, but I
> still get the same error. I used profiler to trace the memory leak, and found
> the following kafka classes to be the cause for the memory leak. Please let
> me know if you need any additional information to debug this issue.
> kafka.server.FetcherLagMetrics
> kafka.consumer.FetchRequestAndResponseMetrics
> kafka.consumer.FetchRequestAndResponseStats
> kafka.metrics.KafkaTimer
> kafka.utils.Pool
