Hi Ben, 

IMO, this falls under this text:  

      A heartbeat-interval of 30 seconds may be considered as too chatty
      in some deployments.  For such deployments, DOTS agents may
      negotiate longer heartbeat-interval values to prevent any network
      overload with too frequent keepalives.

Isn't it?

Cheers,
Med
