youtube live broadcast lifeCycleStatus stuck on 'liveStarting'

I'm trying to figure out what i'm doing wrong when broadcast to live. I have my apk on my android phone stream to youtube. I have no problem streaming for the first time. But if I stop it for about 2 - 3 minutes, and stream again, the lifeCycleStatus of the boardcast keep stay at "liveStarting" and my video is not visible to audience. If I stop long enough, restart stream, the status will go 'live' in about 10 seconds. I have enableMonitorStream disable, and also try LiveBroadcasts.Transition, but it return error redundantTransition. But the lifeCycleStatus wouldn't turn to 'live'. I also try create a new live broadcast and live stream and change the status to 'live' manually, but both get stuck on 'liveStarting'.

How to send 1 million of push notification (APNS) within few second using PushSharp as webservice?

to do that i made a web service to send push (by referencing PushSharp library). I request web service through my web application. i retrieve list of device token from database(using web application) send to web service using for loop to send push. and get result/exception for each one. This process is very slow and take long long time to send notification. If anybody suggest me to what should i do i will be grateful to you.
public ActionResult SendNowToken(int certificateInfoId, string message, string certificate, int badgeNo, int pushtype, string password, string countryJsonString)

I use this code within my User class. Every time a new user signs up using Facebook, this gets executed by calling get_user_data() within the User constructor.
For the below example to work for you too, you'll need an access token with the following permissions:
user_friends
email
Constants:
private ArrayList<HashMap> user_fb_friends;
private final String FIELDS = "id,first_name,last_name,name,gender,locale,timezone,updated_time,email,link,picture,friends{id,first_name,last_name,name,gender,updated_time,link,picture}";
private final String USER_FB_ID_TAG = "id";
private final String F_NAME_TAG = "first_name";
private final String L_NAME_TAG = "last_name";
private final String FULL_NAME_TAG = "name";
private final String GENDER_TAG = "gender";
