Error description

  • During tests of an XMS .NET application using a WebSphere MQ
    Client for Windows, Version 7.0.1.8, the asynchronous message
    delivery in unmanaged mode is not working as expected. All the
    registered message listeners under a single session do not
    receive messages. For example, if there are 4 message listeners
    registered, only 1 message listener recieves messages and the
    other 3 message listeners do not receive any messages.
