      Description

      Mongomirror suffers from the same problem as in SERVER-30724. mongodump may as well.

      To fix, we need to do a forward scan query on the oplog to ensure that all previous operations are committed, like this: https://github.com/mongodb/mongo/commit/b64de307169891f859c29f207e712ed0eb3cd2a2#diff-8fb68c68574d7ec92d5a7f9682c436ecR363
