Subject [jira] Commented: (CXF-2002) Server async jms transport needs dynamic mechanism to throttle message consumption

Sergey Beryozkin commented on CXF-2002:
---------------------------------------

Hi Freeman - thanks for submitting these changes in a single patch...They're now in 2.0.x,
2.1.x, trunk.

Hi Ron : can you please give it a try now in your own production environment ? 

I won't close this JIRA at the moment  - please get back and let us know if the provider fix
works for you and if you reckon it is worth investigating the possibility of restarting DLMC.
In meantime I'll investigate the apparent leakage Freeman observed.

thanks, Sergey

> 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.
