Error: CMSMQSink::Poll() - MQOpenQueue failed: c00e0009
If running multiple portals with XPS, make sure that there are unique queuescreated in MSMQ for each portal.
When the Async Message Processor begins to pull messages out of the queue, it places an exclusive lock on that queue so that no other process can pull messages out (receive) of the queue. This is normally not a problem since theAsync Message Processor is the only process pulling the messages out of the queue. If running multiple portals on the same machine, using the same ProccessQ, the Async Message Processor is multi-threaded, which means as one thread places a lock on the queue, the other threads cannot use the queue.
