    Description

      After SERVER-29030, we cancel our own heartbeat requests if we receive a heartbeat request that announces a new primary. Since we don't update our knowledge of the primary when we receive a heartbeat request, it seems possible to continuously schedule and cancel our heartbeat requests. As a result, a node in initial sync may not be able to find a sync source, because it has not successfully received 2N heartbeats from other nodes, and eventually the node will shut down.
