recommended FPM Max_children setting?

[sunhochoi]

Hello, 

Recently I had to have my server restored and many of the settings went to default.  Now my website keeps going down periodically due to the server reaching  FPM  max_children setting.  I've tried, 20, 40 and now at 80. 

Can anyone tell me if there is a recommended setting for magento2 stores?  

Thank you!

There's no default or recommended value for Magento 2 as it depends on your server (usually the RAM you have) and your particular store.

This is a good article on how to determine the ideal number of children processes for PHP-FPM.
