    Description

      The current default wc for dbCheck is w: 1. This has the potential to flood the oplog, which may increase secondary lag. We should consider using implicitDefaultWC or CWWC if it is set by default for dbCheck to match any other write without an explicit write concern, which will naturally flow control dbCheck to not starve regular writes.
