Hi,

I know this is a difficult question to answer outright, so really I'm just looking for some tips. I have a virtual hosting setup running EZP 3.3-2 (I have to use this version until 3.4 comes out stable, because PHP is compiled as CGI). This setup also has a memory limit of 16MB, which isn't quite enough.

One of the areas of my site runs out of memory and some other areas don't load first time. I think this is something that I'm ultimately going to have to fix with an upgrade of EZP to a less 'memory intensive' version of EZP (i.e. 3.4 when it comes out).

In the meantime, can anyone give me some tips on how to reduce memory usage?

The error messages I get are fairly standard stuff:

Exhausted memory in kernel/classes/ezcontentobjectattribute.php
Exhausted memory in kernel/classes/ezpersistentobject.php

Are these errors usually to do with the design of the templates, or the complexity of objects in the database?

Thanks in advance,

James

Ah! No worries, I stumbled accross this PHP function:

ini_set( "memory_limit", "20M");

Which set the php memory limit to 20MB and sets it back to normal once the script has finished running. Should have read the docs really!
