Push notification not propagating to multiple devices in iphone app?

I want to broadcast a push message to multiple devices. Currently I can send messages if there are only 2 (1 or 2) device tokens in the database table. For 3 or more device tokens, I cannot send push messages. It doesn't even send messages to the previously added 2 devices. Side by side, I see messages as delivered, but they are not actually being delivered.

I tested it on both developer profile and distribution profile, but on both I can only send messages if only 1 or 2 devices are stored in the DB table.

In both cases, I used a single App ID that is configured for development and distribution.

My server side php code looks like this:

<?php
error_reporting(0);
 include 'classfiles/Tokens.php';

if(isset($_POST))
{

$sender = $_POST['sender'];
$message = $_POST['message'];


$token = new Tokens;
$arrtokens = $token->getTokens();


$devicetoken = $_POST['device_token'];

// Settings
$apnsCert = 'test.pem';//To be changed
$apnsHost = 'gateway.push.apple.com';//To be changed
$apnsPort = 2195;

// Connect to Apple Push Notification server
$streamContext = stream_context_create();
stream_context_set_option($streamContext, 'ssl', 'local_cert', $apnsCert);
stream_context_set_option($streamContext, 'ssl', 'passphrase', 'test123');
//60 -> timeout in seconds
$apns = stream_socket_client('ssl://' . $apnsHost . ':' . $apnsPort, $error, $errorString, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $streamContext);
if (!$apns) {
    die('Error creating ssl socket');
}

stream_set_blocking ($apns, 0);

echo 'Connected to APNS' . PHP_EOL;

if(is_array($arrtokens))
{
    //foreach($arrtokens as $key=>$deviceToken)
    for($i=0;$i<count($arrtokens);$i++)
    {

        $incrementcount = 0;
        $tokenid = $arrtokens[$i][0];
        $badgecount = $arrtokens[$i][1];
        $incrementcount = $badgecount+1;

        // Prepare payload
        $payload = 
        array(
            'aps' => array(
            'alert' => $message,
            'badge' => $incrementcount,
            'sound' => 'default',
            'sender' => $sender
            )
        );
        $payload = json_encode($payload);

   /*
        // this was also working 

        $apnsMessage =
