php 5.5.3 php-gd: Unable to load dynamic library '/usr/lib64/php/modules/'

Hey there,

Ive got a droplet with 512MB ram and when i try to execute php, i get the following error:

PHP Warning: PHP Startup: Unable to load dynamic library ‘/usr/lib64/php/modules/’ - cannot map zero-fill pages: Cannot allocate memory in Unknown on line 0

When i upgrade to a 1.024mb droplet all is well, but its a bit weird that i need 1024mb just to use php-gd. I remember installing php on one of my first computers with just 128mb of internal ram. With php-gd (it was php4 so i imagine a bit smaller but this is just weird)

Does anyone have a suggestion? I am running on CentOS 6.4/64bit with a NGINX webserver and mysql, ive used this REPO

anyone an idea?

You might be loading large images using the php5-gd module which is causing your system to run out of memory.

Your droplet is running out of memory, try adding swap: <br> <br>
