limiting memory per user / php-cgi process

[Catscrash]

I seem to have a problem in one of my clients php-scripts. every now and then it starts eating up all 8G of memory and the 2g of swap as well. It's always the same user and only one php-cgi process.

Until the user fixes that script, what can i do to prevent one process from eating up all the system's memory?

And why doesn't the "memory_limit = 512M" setting in /var/www/fcgi/user/php5/php.ini work? A phpinfo.php in the users page shows

memory_limit 512M 512M

thanks for any help

Maybe because it's limit for php script, not for cgi process, which can process few php scripts (and any of them can consume up to 512 Mb). Use /etc/security/limits.conf to set global limits.

For solving your problem you can do some steps may be it will help you.

1. Changing memory_limit globally from php.ini
This is the simplest and most obvious method. You just edit your php.ini and change the memory_limit to whatever you need. For ex:
memory_limit = 32M
2. Changing memory_limit using .htaccess for a single folder/vhost
php_value memory_limit 64M
3. Changing memory_limit inside a single php script.
ini_set('memory_limit', '64M');
