If the queue in question has one of the following statuses, it does not stop immediately: Indexing, Optimizing, Merging, Replicating, Repairing, Rolling Back. The queue server then completes the current activity before suspending the queue. Whilst it is still active, the queue has the status <activity> Suspend in Progress.
If you want the queue server to continue processing the queue, you have to reactivate it using the Activate function.
