Question Error 503 after changing to "FPM application served by..."

[tanasis]

Server operating system version

AlmaLinux 8.10

Plesk version and microupdate number

Version 18.0.61 Update #5

Hello,
on my webserver I had high traffic websites with PHP as "Dedicated FPM application served by Apache / nginx" and I had high CPU.
I changed 4 of them to "FPM application served by Apache / nginx" (no Dedicated) and then some sites start showing Error 503.
I think to change the PHP-FPM settings globally, I'll have to increase the values.

Where can I find the globally settings in Plesk?

You mean for all subscriptions? You can adjust those in the Service Plans.

Yes you are right.

What do you suggest for bellow settings to avoid Error 503 ?

 

[Kaspar@Plesk]

I don't have recommendations. But perhaps any of the suggestions posted here might help you.

Is there a global configuration for apache or only in Service Plans ?

The only way to raise PHP-FPM children is from Service Plans? How many pm.maxchildren/request apache can he handle?

No, you can adjust it per domain. But if you want to adjust it for multiple domain you adjust it via the Service Plan.

Maybe this support article helps: https://support.plesk.com/hc/en-us/...ulate-pm-max-children-value-on-a-Plesk-server
