I have a strange problem that's been randomly showing after ISPConfig 3.1 upgrade. Every now and then I get PHP open_basedir warnings that file from a different client and website is not within allowed path(s): [Wed Oct 19 07:56:03 2016] [error] [client x.x.x.x] FastCGI: server "/var/www/clients/client3/web47/cgi-bin/php5-fcgi-*-443-beta.z-trading.fi" stderr: PHP message: PHP Warning: file_exists(): open_basedir restriction in effect. File(/var/www/clients/client18/web119/web/wp-includes/Requests/Hooks.php) is not within the allowed path(s): (/var/www/clients/client3/web47/web:/var/www/clients/client3/web47/tmp:/var/www/beta.z-trading.fi/web:/srv/www/beta.z-trading.fi/web:/usr/share/php5:/tmp:/usr/share/phpmyadmin:/etc/phpmyadmin:/var/lib/phpmyadmin:/usr/share/php) in /var/www/clients/client3/web47/web/wp-includes/class-requests.php on line 145 [Wed Oct 19 11:53:09 2016] [error] [client x.x.x.x] FastCGI: server "/var/www/clients/client3/web72/cgi-bin/php5-fcgi-*-80-entranze.net" stderr: PHP message: PHP Warning: file_exists(): open_basedir restriction in effect.

I've seen these mostly with Wordpress sites, but something similar is happening with other PHP-sites (although not caught in logs). It seems that Apache or PHP is executing some requests with other vhosts permissions. Any idea what might be causing this? Or how to debug it?
