PHP5-FPM reload from web browser: Internal server error 500

PHP5-FPM reload from web browser: Internal server error 500

I am creating a free shared hosting service for fun and learning. I made a
simple form where the user enters the subdomain and ftp password. When the
user hits submit, a script generates a linux user, encrypts the entered
password with crypt() then sends the data to a linux script. Here is the
wrong part of the full script:
echo "[$1]
user = $1
group = $1
listen = /var/run/sock_$1.sock
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
php_value[disable_functions] = \"phpinfo, system, exec, shell_exec,
passthru , ini_alter, dl, pfsockopen, openlog, syslog, readlink, symlink,
link, leak, fsockopen, popen, escapeshellcmd, apache_child_terminate
apache_get_modules, apache_get_version, apache_getenv,
apache_note,apache_setenv,virtual\"
php_value[open_basedir] = \"/home/$1:/home/$1/tmp\"" | sudo /usr/bin/tee
/etc/php5/fpm/pool.d/$1.conf;
sudo /usr/sbin/service php5-fpm reload;
As you can see it creates a PHP-FPM pool then reloads the service. When I
manually create the pool and also manually reload FPM, it works fine, the
new website loads with no problem. The problem that I noticed if I comment
out the reload line it creates the pool so there is no problem with file
writing but with reloading.
So when I submit the post with all the data, it has Internal server error
500.

Any ideas? Thanks in advance!
