    Looking at 
https://github.com/apache/mesos/blob/9f6ccbd41a55846e54297ecb31fddbeee3be50c9/src/master/master.cpp#L6851-L6865
 I think that this method will be called only if the agent tries to register 
using an already known PID (IP + port).
    
    `Master::_registerSlave()` has a comment with a bit more detail:
    
    ```
          // The slave was previously disconnected but it is now trying
          // to register as a new slave.
          // There are several possible reasons for this to happen:
          // - If the slave failed recovery and hence registering as a new
          //   slave before the master removed the old slave from its map.
          // - If the slave was shutting down while it had a registration
          //   retry scheduled. See MESOS-8463.
    ```
