Hi,
Here is the link and snippet of a WAS problem. Any thoughts how to overcome this ?

There is a known design limitation with the MDB support in WebSphere MQ when multiple Java Virtual Machines (JVMs) attempt delivery from the same queue, as will be the case if you use multiple application servers, as described above, or if you are accessing a queue hosted on a central queue manager from several application server instances.

thanks

From your same article

Although this situation has occurred in the field, it is one that is rarely observed. If encountered, the solution is to use a separate queue for each application server and use some distribution mechanism to fan out requests between queues.
