Laravel 框架下 DB 事务提交后, 数据丢失了怎么解决?

class PaymentController extends Controller
{
    //....
    public function store(CreateRequest $request)
    {
        $attributes    = $request->input();
        $paymentConfig = PaymentConfig::findOrFail($attributes['payment_config_id']);
        $order         = Order::byNumber($attributes['order_number'])->firstOrFail();
        $content       = \DB::transaction(function () use ($attributes, $paymentConfig, $order) {
            $currency_code                         = 'CNY';
            $amount                                = $attributes['amount'];
            $paymentTransaction                    = new PaymentTransaction();
            $paymentTransaction->payment_config_id = $paymentConfig->id;
            $paymentTransaction->order_id          = $order->id;
            $paymentTransaction->currency_code     = $currency_code;
            $paymentTransaction->amount            = $amount;
            $paymentTransaction->details           = [];
            $paymentTransaction->state             = PaymentTransaction::TRANSITION_REQUEST_PAYMENT;
            if (!$paymentTransaction->save()) {
                throw new HttpException(500, 'Save payment transaction failed.');
            }
            $response_content = $this->paymentManager
                ->setPayment($paymentConfig)
                ->orderRequest($order, $amount, $currency_code);
            if (!$response_content) {
                throw new HttpException(500, 'Request payment transaction failed.');
            }
            $details = ['response' => $response_content];
            event(new Created($paymentTransaction, $details));
            return $response_content;
        });
        return [
            'data' => $content
        ];
    }
}   

以上是我在为订单创建支付方式的时候的代码.
客户端拿到了我的响应, 但是我数据库里面对应的记录居然不见了, 而且对应的自增主键也跳过了, 直接从415 变成了 417, 416的数据找不到, 但是客户端是正确获取到我的响应了.
整个事务里面就做了一个插入支付方式流水的操作, 中间有做锁表操作.
应用程序的log里面也没看到对应时间段内的异常

这种现象也不是平凡发生, 目前就碰到一次, 烦请有经验的朋友指点一下.
