Subject Re: ActiveMQ out-of-order redelivery - resource adapter
Date Wed, 22 Oct 2014 20:18:51 GMT

I've created a patch which blocks the session until the redelivery timeout
by stopping the session executor's queue.

I have an automated test which can check the order of the messages, I'll
leave it running for the night.

The tool creates messages and dispatches them to a queue with exclusive
consumer on. They put it into a queue with 40 consumers with message
grouping. The consumers will forward it back to the tool again. 3% of the
messages will throw an exception during processing for the first time. 
Results are promising after 50k messages. (no out of order messages). 

I also tried master-slave fail-over and application server fail-over while
the tool was running. Is it normal to get duplicated messages in case I kill
AMQ or the APP server with -9?
