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

             Summary: camel-kafka - file descriptor leak
                 Key: CAMEL-16832
                 URL: https://issues.apache.org/jira/browse/CAMEL-16832
             Project: Camel
          Issue Type: Improvement
          Components: camel-kafka
    Affects Versions: 3.11.0
            Reporter: Jens Kordowski


The kafka consumer leaks, if the following conditions are met:
 # consumer.poll() throws an exception (i.e. TLS handshake issue)
 # PollOnError is set to RECONNECT

 

The run() method will execute another doInit(), if reconnect is set to true and the doInit() method will create another consumer. The "old" consumer does not unsubscribe and is not closed. It will hold on to 4 (I think) file descriptors, so after reiterating these reconnects many times, finally running into a "too many files" exception.
