I'm setting up nginx and php7.0-fpm on Ubuntu 16.0.4. I haven't used nginx and php7.0-fpm combo before so I was following a number of guides. The guides I found all recommended adding the following config option to the www.conf file for php7.0-fpm

emergency_restart_threshold = 10
emergency_restart_interval = 20s

(the values are just placeholders for the time being)

The problem is when I try to restart php7.0-fpm after adding those options it's fails to start with the following error implying that those options are no longer valid.

ERROR: [/etc/php/7.0/fpm/pool.d/www.conf:414] unknown entry 'emergency_restart_threshold'

Do these options still exist in some form and if so what have they changed to? If they don't what is the alternative to make php7.0-fpm automatically restart.


Looks like these options need to be set in /etc/php/7.0/fpm/php-fpm.conf rather than /etc/php/7.0/fpm/pool.d/www.conf as some sources cited.

  • You can set them in pool.d also but must define [global] section before that. Without section FPM won't start. Tested on php7.1-fpm ubuntu (server 18). – hrvoj3e Jan 9 at 13:01
