Laravel 4.2 と IronMQ2 を使用しています。何らかの理由で、ジョブをランダムに 2 回送信しています。私のメーラーには、次のものがあります。
Queue::push('MailController@fire', ['email' => $email, 'subject' => $subject, 'view' => $view, 'data' => $data, 'attachment' => $attachment]);
$job->delete()呼び出しのすぐ上にある MailController の内部にログインすることで、複数回送信していることがわかります。

ご覧のとおり、すべてのジョブではなく、複製されたジョブは同じ秒で実行されます。これを防ぐ方法はありますか？メールが何度も送信される原因となっています。
