+; Choose how the process manager will control the number of child processes.
+; Possible Values:
+;   static  - a fixed number (pm.max_children) of child processes;
+;   dynamic - the number of child processes are set dynamically based on the
+;             following directives. With this process management, there will be

+;             pm.start_servers     - the number of children created on startup.

+; This value sets the limit on the number of simultaneous requests that will be
+; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
+; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
+; CGI. The below defaults are based on a server without much resources. Don't
+; forget to tweak pm.* to fit your needs.
+; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
+; Note: This value is mandatory.
+pm.max_children = 5
