Hi I am running multi php ver with ispconfig with Ubuntu 18 /etc/php/8.1/fpm/php-fpm.conf) /etc/php/7.2/fpm/php-fpm.conf) /etc/php/7.0/fpm/php-fpm.conf) /etc/php/5.6/fpm/php-fpm.conf) my website recently keep getting: 502 Bad Gateway nginx/1.18.0 (Ubuntu) for 15 to 30 mins, then back to normal. I google and see that I may need to change the setting in /usr/local/php/etc/php-fpm.conf for below, but there is no such path in my server, and I could not find these setting. where are they? pm.max_children=5 request_terminate_timeout=60 --------------------------------------------------- root@ECS1:~# netstat -anop | grep php-cgi | wc -l 0 root@ECS1:~# netstat -anpo | grep php-fpm | wc -l 57 root@ECS1:~# ps aux | grep php-fpm www-data 756 0.0 0.0 530148 7256 ?

Perhaps they are in Code: /etc/php/8.1/fpm/php-fpm.conf) /etc/php/7.2/fpm/php-fpm.conf) /etc/php/7.0/fpm/php-fpm.conf) /etc/php/5.6/fpm/php-fpm.conf)
Hi I see the log with this error, which causes the 502 error. Is there any setting in ispconfig server reached max_children setting (10), consider raising it Ispconfig has setting for these.
