    Hello! I have just tested the solution on my Plesk Onyx (CentOS 7)

    # grep -iR 'FcgidMaxProcesses' /etc/httpd/
    /etc/httpd/conf.d/fcgid.conf: FcgidMaxProcesses 20   <----------------before changing

    # vi /etc/httpd/conf.d/fcgid.conf
    # grep -iR 'FcgidMaxProcesses' /etc/httpd/
    /etc/httpd/conf.d/fcgid.conf: FcgidMaxProcesses 40   <----------------after changing

    # service httpd restart

    # grep -iR 'FcgidMaxProcesses' /etc/httpd/
    /etc/httpd/conf.d/fcgid.conf: FcgidMaxProcesses 40   <----------------after Apache restart

    Please describe a scenario when this setting was changed to original value.

    These values are not enough to resolve the issue.

    I've seen multiple cases on multiple servers where you need to increase these value as well, and maybe others :

    Thank you for your comment. Indeed, in some cases it is needed to increase some of the values to even greater values, it all depends on the server configuration and the server load. However, the best way is to increase values little by little, because setting up very big values may affect the server performance drastically.
