The first thing server owners tend to do for an immediate fix, is to restart the PHP-FPM service. But simply restarting the service is only a band-aid solution, and you will soon see the load spiking McDVOICE

Hi I changed my pm.max_children from 10 to 20 across all the domain names, now the plesk dashboard is so slow. Is there any connection on that?

Make sure that mysql service is up and running.

Unfortunately I dont have the ssh access. So I cannot confirm that. I changing the pm.max_children can be the cause of it?

 

[IgorG]

PHP setting pm.max_children has nothing to do with MySQL operation. If only indirectly.
