Producer hanged when sending 6M ByteMessage

[yanhongsan <xi...@163.com>]

Hello, everyone. I download the latest version ActiveMQ5.1.  When I send
about 6M  ByteMessage to a queue 100 times loop, I found the producer hanged
after sending a message. The following is my code:

}

the bb.zip file is about 6M. When I run the class, the result is :
Sending message: msg 0
Sending message: msg 1
But once I consume the queue "eastsoft", I can send all the 100 files.
