Memory allocation error: script or PHP setting at fault?

[schwim]

Hi there everyone,

I recently moved a site from a server with , Apache 1.3/PHP 4.4.4/MySQL 4.2.1 to one with Apache 2/PHP 5.2.1/MySQL 5 and have run into a problem.

The site is a PostNuke site and I had to make some changes to the session function to get it to run on PHP 5.2, so I know that it wasn't written for that late a version. The problem that I run into now is that often, I end up with a memory allocation error:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 47 bytes) in /home/site/public_html/modules/gallery/classes/Album.php on line

It's usually in the gallery portion of the site because it uses more memory than most scripts.

The issue I have is that I tried to mimic the PHP settings of the old server on the new, using the same memory allocation values. I never had these errors on the old site.

My question is this. Am I dealing with a PHP issue, in which I need to alter something in the settings to account for the later version of PHP or do you think I'm dealing with a script that's unable to work on the later version of PHP?

Any thoughts would be welcome,

Could be php, could be an issue in your code. Check for infinite loops, bad or incompatible extensions, and make sure that the memory_limit is proper (i.e. "128M" not "128MB" or "128Mb").

Thanks very much for your reply. I tried to match the settings between old and new PHP installs. What would you suggest a safe memory limit is for a standard server install? I know every one requires different allocations, but what's a good starting point in your opinion?

thanks,

The default... 128M
