3.1.5.1 Pending Request Cleanup Timer Event
When the Pending Request Cleanup Timer (section 3.1.2.2) expires, for the PendingRequestEntry (section 3.1.1.2) ADM element instance iPendingRequestEntry associated with this timer, the server MUST:
Find the OpenQueueDescriptor ADM element instance fOpenQueueDescriptor by comparing iPendingRequestEntry.QueueContextHandle with the Handle ADM attribute for all OpenQueueDescriptor ADM element instances maintained by the local QueueManager ADM element instance.
Find the corresponding Message ADM element instance fMessage by comparing iPendingRequestEntry.LookupIdentifier with the MessageReference.Identifier ADM attribute of all MessagePosition ADM element instances in fOpenQueueDescriptor.QueueReference.MessagePositionCollection.
Generate a Dequeue Message End ([MS-MQDMPR] section 3.1.7.1.12) event with the following inputs:
iQueueDesc := fOpenQueueDescriptor.
iMessage := fMessage.
iDeleteMessage := false.
Remove the PendingRequestEntry ADM element instance iPendingRequestEntry from the PendingRequestTable (section 3.1.1.3) ADM element, and cancel the timer.
