    Description

      Since we no longer kill readers and close their connections on stepdown, the nodes syncing from the primary may not have a chance to choose a new sync source even if chaining is disabled.

      SERVER-21537 has similar symptoms when the heartbeats are stale. Both of them can be addressed in the Smart Chaining project.
