Applicable to:
- Plesk Obsidian for Linux
Symptoms
- PHP-FPM service fails to start on Plesk Onyx 17.8.
- Error in
/var/log/plesk-phpXX-fpm/error.log:CONFIG_TEXT: ERROR: An another FPM instance seems to already listen on /var/www/vhosts/system/subdomain.example.com/php-fpm.sock
ERROR: An another FPM instance seems to already listen on /var/www/vhosts/system/subdomain.example.com/php-fpm.sock
ERROR: FPM initialization failed
ERROR: FPM initialization failed - Subdomain was created via XML API.
- Non-system PHP handler is assigned to the subdomain mentioned in the error message. But configuration file from system PHP handler presents:
# find /etc /opt -name subdomain.example.com.conf
/etc/httpd/conf/plesk.conf.d/vhosts/subdomain.example.com.conf
/etc/nginx/plesk.conf.d/vhosts/subdomain.example.com.conf
/etc/php-fpm.d/subdomain.example.com.conf
Cause
Incorrect PHP configuration file was generated during subdomain creation via XML API.
Plesk bug PPPM-10022 which will be fixed in future updates.
Resolution
Apply one of the workarounds below:
- Log in to Plesk server via SSH
- Remove the excessive configuration file:
# rm -f /etc/php-fpm.d/subdomain.example.com.conf
OR
- Log in to Plesk
- Go to Domains > subdomain.example.com > PHP Settings
- Switch to FPM by OS vendor and back to the desired PHP version

@Luis Plesk bug PPPM-10022 is still open and not resolved. The article that helped in your case describes similar but not the same issue. Glad to know you found the solution!
