    Description

      On a single Secondary node of a replica set, after resizing a 1+ TB oplog a total of three (3) times (-> 51200 MB -> 25600 MB -> 5120 MB), the oplog dropped to zero/empty, and the mongod log shows no indication of having restarted.

      Please help us understand why the oplog unexpectedly became empty.
