Issue Plesk does not generate the dedicated phpfpm8.1 pool serverd by nginx. It fails silently leaving a broken stack behind

Plesk version and microupdate number

Newest Obsidian

It took many days to track down the root casue of my extreme issues I was facing with the server. Now I clearly identified that if I apply phpfpm8.1 served by nginx in the plesk panel and then apply it, the pool is not generated in /var/www/vhosts/system/domain/etc thus the pool configuration is missing and it falls back to some default pool making the whole stack crashing and laggin all the time incl. mariadb freeze and affecting other sites on this server with the same db. Thats really terrible from plesk. I am really disappointed.

I am unable to reproduce the described behavior on a test Ubuntu 22.04 server with Plesk Obsidian 18.0.69:

php-fpm: master process (/var/www/vhosts/system/10-69-45-189.qa.plesk.tech/etc/php-fpm.conf)

Without any additional details about the exact configuration on your server, any logs, and details on what tests you performed to come to the conclusion it is really difficult to help. Even with such details, it is relatively complicated to address such an issue without server access. My advice would be to get in touch with Plesk support and provide them with direct access to the server in question for effective investigation.
