Date Wed, 06 Mar 2019 07:20:35 GMT
limeng created KAFKA-8049:

             Summary: remove KafkaMbean when network close
                 Key: KAFKA-8049
                 URL: https://issues.apache.org/jira/browse/KAFKA-8049
             Project: Kafka
          Issue Type: Bug
          Components: clients, core
    Affects Versions:,,
            Reporter: limeng
             Fix For: 2.2.1

the  broker server will be oom when 
 * a large number of clients frequently close and reconnect
 * the clientId changes every time when reconnect,that gives rise to too much kafkaMbean
in broker

the reason is that broker forget to remove kafkaMbean when detect connection closes.
