Subject Messages order corrupt.
Date Mon, 13 Jul 2009 10:56:17 GMT

Hi everyone.
We have an application using ActiveMQ for messaging. The order of messages
is significant for us.
There is a problem when we have a lot of messages hanging in a queue:
1. Generate a lot of messages (around 20000).
2. Start some consumer. Leech them.
3. Stop the consumer. Mostly at this stage the counter for messages gets
wrong: we have something like 
Number Of Pending Messages -12
Number Of Consumers              0
Messages Sent                 37500
Messages Received           37512
In web console.
4. Delete this queue in web console.
5. Repeat steps 1, 2
We see that consumer gets messages not in the same way as the producer puts

ActiveMQ ver.5.2.0
Java version 1.6.0_13
OS WinXP + SP3
