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

             Summary: Kafka brokers can't communicate with each other, reports Error sending fetch request , java.io.IOException: Connection to 2 was disconnected before the response was read
                 Key: KAFKA-13317
                 URL: https://issues.apache.org/jira/browse/KAFKA-13317
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 2.8.0
            Reporter: priya Vijay


We are running kafka 2.8 and have 3 brokers in our cluster. After running fine for few hours, broker logs show bunch of errors like following.  Looks like the brokers are not able to communicate with each other

*[2021-09-22 00:00:47,274] INFO [ReplicaFetcher replicaId=0, leaderId=2, fetcherId=0] Error sending fetch request (sessionId=9629724, epoch=60615) to node 2: (org.apache.kafka.clients.FetchSessionHandler)*
*java.io.IOException: Connection to 2 was disconnected before the response was read*

*2021-09-22 00:00:47,284] WARN [ReplicaFetcher replicaId=0, leaderId=2, fetcherId=0] Error in response for fetch request (type=FetchRequest, replicaId=0, maxWait=500, minBytes=1, maxBytes=10485760, fetchData={}, isolationLevel=READ_UNCOMMITTED, toForget=, metadata=(sessionId=9629724, epoch=60615), rackId=) (kafka.server.ReplicaFetcherThread)*
*java.io.IOException: Connection to 2 was disconnected before the response was read*
*at org.apache.kafka.clients.NetworkClientUtils.sendAndReceive(NetworkClientUtils.java:100)*

any pointers on how to work around these? are there any configuration on broker that will help with these issues?
