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
