On my last post I was uploading some images to include in the post using WordPress. I noticed in my error logs that while resizing the images the PHP script attempts to raise the memory limit.
Feb 26 22:52:29 host suhosin: ALERT - script tried to increase memory_limit to 268435456 bytes which is above the allowed value (attacker 'XXX.XXX.XXX.XXX', file '/var/www/wordpress/wp-admin/includes/image.php', line 161)
This is fair enough and is a good idea for security and to stop your server getting overloaded by a single script. So I looked into how to fix this and its a very simple process.
You need to edit your suhosin config. I am doing this under Ubuntu 9.04 mine is located ‘/etc/php5/apache2/conf.d/suhosin.ini’. To fix it for WordPress just add the setting `suhosin.memory_limit` to the config file with the appropriate value in the case of WordPress it needs to be set to 256.
Your config should end up looking like this
extension=suhosin.so [suhosin] suhosin.memory_limit = 256M
that is it really very simple. I am going to have a bit of a tweak with suhosin config later I think the default config can be improved a lot.
