On the Deployment process there is always a Quick Deploy associated to the Deployment Path, this Quick Deploy allows users to set specific contents , like pages, to be deployed in the timeframe of the Quick Deploy job.
Sometimes the Quick Deploy job fails and the items causing the problem stay in the quick deploy pool and can make the deploy fail. But there is hope, we can delete the items from the Quick Deploy Items List, because these items are listed in a Sharepoint List (cool!).
