| Are you also testing the RC after the MQOPEN? Perhaps it is the MQOPEN that is failing once in a blue moon. |

Here's my opinion:
You should be able to have several clients connect to the one channel with no performance issues. Of course, the exact number will vary depending on how many clients you have, ... |

When you issue a reply message, you stay connected to your local queue manager. You can "open" the replyToQ, even if that queue is on another queue manager.

The easiest way I can think of offhand is to do the MQGET under a UOW (unit of work). It's perfectly valid, even for a single message.
On the MQGET call, you would need to set MQGMO_SYNCPOINT. ... |

If this can be done, it would be a function of the operating system, not MQ. As such, the answer will vary depending on the platform.
