FIX: Dehydrated Schedules Do Not Rehydrate When Correlation Messages Arrive in Message Queuing (820539)

SYMPTOMS

A correlational message is a message that uses the instance ID of a running XLANG schedule instance as its message label. This article discusses a problem that occurs in the following scenario:

You have several XLANG schedule instances in the dehydrated state that are waiting for correlation messages to arrive in a Microsoft Message Queuing (also known as MSMQ) queue. These dehydrated XLANG schedule instances share a single Message Queuing queue.
When several correlation messages arrive, only one dehydrated schedule instance rehydrates. The remaining schedule instances maintain a dehydrated state although matching correlation messages are waiting to be picked up in the Message Queuing queue.
