I have installed the software in the past on an old provider with no issue but Im trying a number of time on MediaTemple (GRID) and always hit the same wall so finally going to figure out whats going on.

All original Images seem to upload fine and if the images are small it works as expected but if the image is over about 6-7 meg the 3 small versions including thumbnails, are incomplete or missing althogether. Its doing a conversion in most cases so I assume its finding ImageMagick I just need to work out why its creating incomplete images.
There is a log for each image which is reporting no errors.
Someone suggested in might be the host limited CPU and terminating the process.
In the install check for RS I get OK for ImageMagick - Version: ImageMagick 6.7.7-10 2016-12-22 Q16 , althou in the MediaTemple documentation It says ImageMagick is not available to php5 and an opendir must be enabled in php.ini so im not sure if its there or not. When I do add the required line opendir it breaks the page.
I have altered php file max and execution times in htaccess
Any ideas what might be happening
