Description

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.
