Mac os X Error unloading plist

Question

I'm currently using MacOSX 10.8 and I tried to install the built-in php-fpm.

Moreover I want a plist file to start and stop php-fpm on demand. I found this one

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>KeepAlive</key>
    <true/>
    <key>Label</key>
    <string>net.php.php-fpm</string>
    <key>LaunchOnlyOnce</key>
    <true/>
    <key>NetworkState</key>
    <true/>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/sbin/php-fpm</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>ServiceDescription</key>
    <string>PHP FastCGI Process Manager</string>
    <key>StandardErrorPath</key>
    <string>/var/log/system.log</string>
</dict>
</plist>

Where the launchctl (with sudo) -w load works find... When I try to unload I get this error:

launchctl: Error unloading: net.php.php-fpm

I don't really understand why?

UPDATE:

$ sudo launchctl load -w /Library/LaunchAgents/net.php.php-fpm.plist 
$ ps aux | grep php

I found my response inside Homebrew bug tracking system:

https://github.com/josegonzalez/homebrew-php/issues/370

It's about PHP-FPM configuration, we must put PHP-FPM daemonize to no (default = true)
