Amazon S3 upload error: An exception occurred while uploading parts to a multipart upload

I am trying to upload a 30 GB file to Amazon S3 using the AWS PHP SDK.

require('../vendor/autoload.php');

$client = new Aws\S3\S3Client([
'version' => 'latest',
'region'  => 'us-east-1'
]);

$bucket_name = 'My-new-bucket';
$file_name   = 'S3_www_1443369605.zip';

try {  

    $client->upload($bucket_name, $file_name, fopen($file_name, 'rb'), 'public-read');
    echo "File has been uploaded";

    } catch(Exception $e) { 
    echo "File upload error: $e"; 
    }

It works for files up to 7GB. When uploading the 30 GB file I am getting the following error after the script has run for about 2 hours:
