Nette issue after month of running

Hi, I found a following problem.

I installed an Apache 2.4 and PHP 7.0.27 server with PDO MSSQL drivers. I developed a Nette intranet application, which is using in production 24/7 by operators. Application is running correctly.

But: after one month of running, I get the following error:

require(): file:// wrapper is disabled in the server configuration…

Warning: require(): file:// wrapper is disabled in the server configuration in D:\_SERVER_DATA\_web\rwa\vendor\composer\autoload_real.php on line 66

Warning: require(D:\_SERVER_DATA\_web\rwa\vendor\symfony\polyfill-mbstring\bootstrap.php): failed to open stream: no suitable wrapper could be found in D:\_SERVER_DATA\_web\rwa\vendor\composer\autoload_real.php on line 66

Fatal error: require(): Failed opening required ‘D:\_SERVER_DATA\_web\rwa\vendor\composer/../symfony/polyfill-mbstring/bootstrap.php’ (include_path=‘.;C:/_SERVER/php71/’) in D:\_SERVER_DATA\_web\rwa\vendor\composer\autoload_real.php on line 67

After restart Apache, problem will disappear.

It seems to be like there is a problem with PHP require file with full path. I checked PHP.ini configuration and allow_url_fopen is ON and also allow_url_include is ON

I tried to run composer self update, but it not helped.
