      Description

      We have a tag-aware sharded cluster with each node being a 3 member replicaset of which 1 member is hidden.

      In this particular instance, the hidden member keeps switching the sync source between Primary & the other Secondary and rolls back updates after every switch.

      After a couple of such switches and rollbacks, it enters into an invalid/inconsistent state and crashes.

      Attached is the log file for the mongod instance showing this.
