I have a hefty PHP script.

So much so that I have had to do 

ini_set('memory_limit', '3000M');
set_time_limit (0);

It runs fine on one server, but on another I get: Out of memory (allocated 1653342208) (tried to allocate 71 bytes) in /home/writeabo/public_html/propturk/feedgenerator/simple_html_dom.php on line 848

Both are on the same package from the same host, but different servers.

Above Problem solved new problem below for bounty

Update: The script is so big because it rawls a site and parsers data from 252 pages, including over 60,000 images, which it makes two copies of. I have since broken it down into parts.

I have another problem now though. when I am writing the image from outside site to server like this:

try {
    $imgcont = file_get_contents($va); // $va is an img src from an array of thousands of srcs
    $h = fopen($writeTo,'w');
       fwrite($h,$imgcont);
       fclose($h);
    } catch(Exception $e) {
    $error .= (!isset($error)) ? "error with <img src='" . $va . "' />" : "<br/>And <img src='" . $va . "' />";
    }

All of a sudden it goes to a 500 internal server error page and I have to do it again, at which point it works, because files are only copied it they don’t already exist. Is there anyway I can receive the 500 response code and send it back it to the url to make it go again? As this is to all be an automated process?

    Thanks for all your input. I had seperated everything by the time I wrote this question, so the crawler, fired the image grabber, etc.

    I took on board the solution to split the number of images, and that also helped.

    I also added a try, catch round the file read.

    This was only being called from the browser during testing, but now that it is all up and running it is going to be a cron job.

    Thanks Swish and Benubird for your particularly detailed and educational answers. Unfortunately I had no cooperation with the developers on the backend where the images are coming from (long and complicated story).

    Anyway, all good now so thanks. (Swish how do you call a script from the command line, my knowledge of this field is severely lacking?)
