I have an problem increasing memory limit for PHP as Apache module.

If I put following directive in Apache configuration, that work OK:

php_value memory_limit 1.99G

But over 2GB do not work, it's restore this value back to 128MB.

What is the problem here? I need more memory for some PDF related tasks.

Server is Debian 2.6.32-5-amd64 #1 SMP, PHP 5.3.3-7+squeeze13 with 12GB physical RAM.

You can also try this:

ini_set("max_execution_time", "-1");
ini_set("memory_limit", "-1");
ignore_user_abort(true);
set_time_limit(0);

I had the same problem with commandline php even when ini_set("memory_limit", "-1"); was set, so the limit is in php not from apache.

You should check if you are using the 64bit version of php.

Look at this question about Checking if code is running on 64-bit PHP to find out what php you are using.

I think your php is compiled in 32 bit.
