---------------------------------------
Summary: KafkaPerformanceProducer crashes with same transaction id.
Key: KAFKA-7171
URL: https://issues.apache.org/jira/browse/KAFKA-7171
Project: Kafka
Issue Type: Bug
Affects Versions: 1.0.1
Reporter: kaushik srinivas
Running org.apache.kafka.tools.ProducerPerformance code to performance test the
kafka cluster. As a trial cluster has only one broker and zookeeper with 12GB
of heap space.
Running 6 producers on 3 machines with same transaction id (2 producers on each
node).
Below are the settings of each producer,
kafka-run-class org.apache.kafka.tools.ProducerPerformance --print-metrics
--topic perf1 --num-records 9223372036854 --throughput 250000 --record-size
200 --producer-props bootstrap.servers=localhost:9092 buffer.memory=524288000
batch.size=524288
for 2 hours all producers run fine, then suddenly throughput of all producers
increase 3 times and 4 producers on 2 nodes crashes with below exceptions,
[2018-07-16 14:00:18,744] ERROR Error executing user-provided callback on

First machine (2 producers) run fine.
Need some pointers on this issue.
Queires:
why the throughput is increasing 3 times after 2 hours of duration ?
why the other producers are crashing ?
