---------------------------------------
Summary: Kafka Brokers goes down with outOfMemoryError.
Key: KAFKA-6165
URL: https://issues.apache.org/jira/browse/KAFKA-6165
Project: Kafka
Issue Type: Bug
Affects Versions: 0.11.0.0
Environment: DCOS cluster with 4 agent nodes and 3 masters.
agent machine config :
RAM : 384 GB
DISK : 4TB
Reporter: kaushik srinivas
Priority: Major
Attachments: kafka_config.txt, stderr_broker1.txt, stderr_broker2.txt,
stdout_broker1.txt, stdout_broker2.txt
Performance testing kafka with end to end pipe lines of,
Kafka Data Producer -> kafka -> spark streaming -> hdfs -- stream1
Kafka Data Producer -> kafka -> flume -> hdfs -- stream2
stream1 kafka configs :
No of topics : 10
No of partitions : 20 for all the topics
stream2 kafka configs :
No of topics : 10
No of partitions : 20 for all the topics
Some important Kafka Configuration :
"BROKER_MEM": "32768"(32GB)
"BROKER_JAVA_HEAP": "16384"(16GB)
"BROKER_COUNT": "3"
"KAFKA_MESSAGE_MAX_BYTES": "1000012"(1MB)
"KAFKA_REPLICA_FETCH_MAX_BYTES": "1048576"(1MB)
"KAFKA_NUM_PARTITIONS": "20"
"BROKER_DISK_SIZE": "5000" (5GB)
"KAFKA_LOG_SEGMENT_BYTES": "50000000",(50MB)
"KAFKA_LOG_RETENTION_BYTES": "5000000000"(5GB)
Data Producer to kafka Throughput:
message rate : 5 lakhs messages/sec approx across all the 3 brokers and
topics/partitions.
message size : approx 300 to 400 bytes.

These two exceptions are happening across all the 3 brokers continously with
the same kafka configuration.
Broker dies with these exceptions.
Attached the log files for 2 issues of two brokers.
Also attached is the kafka configuration json data being used.
