public InternalDistributedMember advisePrimaryGatewaySender() {
    Profile[] snapshot = profiles;
    for (Profile profile : snapshot) {
      GatewaySenderProfile sp = (GatewaySenderProfile) profile;
      if (!sp.isParallel && sp.isPrimary) {
        return sp.getDistributedMember();
      }
    }
    return null;
  }
I need this boolean to make sure the sender which is volunteer for primary is running. not
running sender should not become primary.
