ErrorException в Laravel [Session]

Question

Не всегда, но очень часто, мой сайт, который сделан с использованием фреймворка laravel, показывает

ErrorException

SessionHandler :: gc (): ps_files_cleanup_dir: opendir (/ var / lib / php / session) не удалось: разрешение отклонено (13)

13.ErrorException ../vendor/symphony/http-foundation/Symphony/Component/HttpFoundation/Session/Storage/Proxy/SessionHandlerProxy.php:93

Это мой SessionHandlerProxy.php

    /**
     * Constructor.
     *
     * @param \SessionHandlerInterface $handler
     */
    public function __construct(\SessionHandlerInterface $handler)
    {
        $this->handler = $handler;
        $this->wrapper = ($handler instanceof \SessionHandler);
        $this->saveHandlerName = $this->wrapper ? ini_get('session.save_handler') : 'user';
    }

    // \SessionHandlerInterface

    /**
     * {@inheritdoc}
     */
    public function open($savePath, $sessionName)
    {
        $return = (bool) $this->handler->open($savePath, $sessionName);

        if (true === $return) {
            $this->active = true;
        }

        return $return;
    }

    /**
     * {@inheritdoc}
     */
    public function close()
    {
        $this->active = false;

        return (bool) $this->handler->close();
    }

    /**
     * {@inheritdoc}
     */
    public function read($id)
    {
        return (string) $this->handler->read($id);
    }

    /**
     * {@inheritdoc}
     */
    public function write($id, $data)
    {
        return (bool) $this->handler->write($id, $data);
    }

    /**
     * {@inheritdoc}
     */
    public function destroy($id)
    {
        return (bool) $this->handler->destroy($id);
    }

    /**
     * {@inheritdoc}
     */
    public function gc($maxlifetime)
    {
        return (bool) $this->handler->gc($maxlifetime);
    }
}
