             Summary: IO exception on windows when high throughput of messages
                 Key: KAFKA-1065
                 URL: https://issues.apache.org/jira/browse/KAFKA-1065
             Project: Kafka
          Issue Type: Bug
          Components: producer 
    Affects Versions: 0.8
         Environment: Windows 7 64bit
            Reporter: Carl Austin
            Assignee: Jun Rao


When a large number of messages are sent per second to a broker on Windows a memory mapping exception occurs and kills Kafka. The exception follows :

This seems to have been mentioned in the past on the Kafka mail list and is an issue related to http://bugs.sun.com/view_bug.do?bug_id=4724038.

Unfortunately this means that we cannot use Kafka on Windows.
