Hey Guys,
hope you are doing well!
In december we installed PHP 8.1 on our Plesk Server, created a new service plan and brought some subscriptions in it.
Since a couple of weeks, these sites are frequently not accessible (504 error) while the sites running on php 7.4 are still up. First it started once in a couple of days, but now the problem sometimes occurs several times a day. A restart of php-fpm 8.1.14 service bring this sites back to life, but just for a time.
Can you please help me to hunt this problem down?
I have already checked a lot of access and error logs, but cant find a major problem. all i find is nginx waiting for informations from apache after the problem occurs.
My first thought was that it might be a problem with pm.max_children - it is currently set to 10 for both php versions.
Thank you very much for your Support!
