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

             Summary: Transactions system test with hard broker bounces fails sporadically
                 Key: KAFKA-5339
                 URL: https://issues.apache.org/jira/browse/KAFKA-5339
             Project: Kafka
          Issue Type: Sub-task
            Reporter: Apurva Mehta
            Assignee: Apurva Mehta
            Priority: Blocker


The transactions hard bounce test occasionally fails because the transactional message copy just seems to hang. In one of the client logs, I noticed:

This suggests that the client has gotten to a bad state which is why it stops processing messages, causing the tests to fail.
