Hi, I'm seeing slow off-heap memory leak in production. I've managed to recreated the scenario in a testing environment - I have one ZooKeeper node and one Kafka Broker (running on same machine). I have one java process which runs a thread which constantly writes to Kafka using 16 KafkaProducer. I see that the resident memory of my java process is slowly decreasing (roughly 250mb every 15 min). When running GC it cleans the heap to 730mb roughly but resident remains high: 2.3gb and increasing steadily. So from that I presume it's a leak of off-heap memory.
I'm little puzzled here since I haven't seen any usage of ByteBuffer.allocateDirect() in the new client code, but I though I'll check with the audience in case you are aware of any issue that might cause it? I'm chasing this leak for several days, and managed to track it down to the code writing to Kafka, so I'm a little desperate :) any help will do. Thanks! Asaf
