<value name="pm">

Sets style of controling worker process count.  
Valid values are 'static' and 'apache-like'  
<value name="style">static</value>

Sets the limit on the number of simultaneous requests that will be served.  
Equivalent to Apache MaxClients directive.  
Equivalent to PHP_FCGI_CHILDREN environment in original php.fcgi  
Used with any pm_style.  
<value name="max_children">200</value>

Settings group for 'apache-like' pm style  
<value name="apache_like">

Sets the number of server processes created on startup.  
Used only when 'apache-like' pm_style is selected  
<value name="StartServers">20</value>

Sets the desired minimum number of idle server processes.  
Used only when 'apache-like' pm_style is selected  
<value name="MinSpareServers">5</value>

Sets the desired maximum number of idle server processes.  
Used only when 'apache-like' pm_style is selected  
<value name="MaxSpareServers">250</value>

</value>

</value>

<value name="chroot"></value>

Chdir to this directory at the start  
<value name="chdir"></value>

Redirect workers' stdout and stderr into main error log.  
If not set, they will be redirected to /dev/null, according to FastCGI specs  
<value name="catch_workers_output">yes</value>

How much requests each process should execute before respawn.  
Useful to work around memory leaks in 3rd party libraries.  
For endless request processing please specify 0

Comma separated list of ipv4 addresses of FastCGI clients that allowed to connect.  
Equivalent to FCGI_WEB_SERVER_ADDRS environment in original php.fcgi (5.2.2+)  
Makes sense only with AF_INET listening socket.  
<value name="allowed_clients">127.0.0.1</value>

Pass environment variables like LD_LIBRARY_PATH  
All $VARIABLEs are taken from current environment
