You can view documents currently in the queue, the document statuses, and the order in which the documents are queued.
Some document versions can be removed from the queue if the SkipFailedDocumentsInLoad setting is enabled for the site. If SkipFailedDocumentsInLoad is enabled, a document that successfully loads any previous failed versions of that document are removed from the queue. For additional details, see Server Manager Site Properties and Settings and Site Settings node properties.
