Yu Yang created KAFKA-6544:
------------------------------

             Summary: kafka process should exit when it encounters "java.io.IOException: Too many open files"  
                 Key: KAFKA-6544
                 URL: https://issues.apache.org/jira/browse/KAFKA-6544
             Project: Kafka
          Issue Type: Bug
          Components: admin, network
    Affects Versions: 0.10.2.1
            Reporter: Yu Yang


Our kafka cluster encountered a few disk/xfs failures in the cloud vm instances. When a disk/xfs failure happens, kafka process did not exit gracefully. Instead, it run into  "<defunct>" status, with port 9092 still be reachable.  when failures like this happens, kafka should shutdown all threads and exit. The following is the kafka logs when the failure happens:
