Hi Sergey,
The good news is until now I can't reproduce the message lost problem.
But another issue I've found is the message leak problem with jms continuation,
let's say the server side recieved 1001 message
then I saw the class instance like (get it by "jmap -histo:live" with jdk6)

never get released, so if sever run after long term, we will encouter the OOM
exception.
I guess this might be another issue, so please create a new ticket if you feel
it's necessary.
Btw, I also see same memory leak problem with cxf http continuation.
Thanks

> Server async jms transport needs dynamic mechanism to throttle message

> Key: CXF-2002
> URL: https://issues.apache.org/jira/browse/CXF-2002
> Project: CXF
> Issue Type: Improvement
> Components: Transports
> Affects Versions: 2.0.9, 2.1.3, 2.0.10
> Reporter: Ron Gavlin
> Assignee: Sergey Beryozkin
>
> Currently, the server-side async jms transport has no mechanism to throttle
> consumption of incoming messages. This becomes problematic in scenarios where
> a large backlog of messages exists on the input queue. In this case, it is
> likely that the cxf server will overload its internal work item queues
> resulting in problems. A dynamic throttling mechanism on the async jms server
> is required to avoid this problem.
