----------------------------------------

             Summary: frequent network_exception trace at kafka producer.
                 Key: KAFKA-13178
                 URL: https://issues.apache.org/jira/browse/KAFKA-13178
             Project: Kafka
          Issue Type: Bug
            Reporter: kaushik srinivas


Running 3 node kafka cluster (4 cores and 4 cpu in k8s).

topics : 15, partitions each : 15 , replication factor : 3. min.insync.replicas : 2

producer is running with acks : "all"

We see frequent failures in the kafka producer with below trace

{"host":"wwwwww","level":"WARN","log":{"classname":"org.apache.kafka.clients.producer.internals.Sender:595","message":"[Producer clientId=producer-1] Got error produce response with correlation id 2646 on topic-partition *wwww-0, retrying (2 attempts left). Error: NETWORK_EXCEPTION","stacktrace":"","threadname":"kafka-producer-network-thread | producer-1"},"time":"2021-08-*04T02:22:20.529Z","timezone":"UTC","type":"log","system":"wwwww","systemid":"3"}

 

What could be possible reasons for the above trace ?
