connect() to unix ... php-fpm.sock failed

[Huskynarr]

I don't know which change that Problem makes, But if more than a handful of people on the server, the CPU load increases enormously and php-fpm collapses after a few seconds.

My Error Log look like this:

[error] 26802#0: *758923 connect() to unix:/var/www/vhosts/system/domain.tld/php-fpm.sock failed (11: Resource temporarily unavailable) while connecting to upstream, client: 179.43.159.26, server: domain.tld, request: "POST /xmlrpc.php HTTP/1.1",

I can't Regex, because this is the Reason for the muddled Rules.


And at the plesk service php-fpm status:

php-fpm: unrecognized service

Any Ideas how can i fix that (or make this easier to read)?

Hope and Thanks for Answers.

Ps. yes i have found the search function, i have read a lot of threads and Blogs, but nothing found or im a idiot.
