Database '%1': While attempting to move to the next or  previous node in a B-Tree, the database engine skipped over %4  non-visible nodes in %5 pages. It is likely that these non-visible  nodes are nodes which have been marked for deletion but which are  yet to be purged. The database may benefit from widening the online  maintenance window during off-peak hours in order to purge such nodes  and reclaim their space. If this message persists, offline  defragmentation may be run to remove all nodes which have been marked  for deletion but are yet to be purged from the database.
