The services of the server stops when scanning Website

Hi all, while using WP Defender to scan website i noticed the server services stop's working (php, nginx,mysql).
I use Webuzo control Panel with my VPS and i have installed WP from the Webuzo control panel which i think the problem with WP Defender is because WP wasn't installed manually.

I know i can change the wp-config.php to reflect the manual installation, but webuzo cp has some cool features to create and manage backups which i use for different purposes of Snapshot.

Should i disable the connection between Webuzo and WP?

Thank you
