I am receiving the following out of memory error: Fatal error: Out of memory (allocated 19922944) (tried to allocate 30720 bytes) in /home/hostitif/public_html/sites/all/modules/print/print.module on line 352

This is for a website that I am moving from one host to another. I was able to move the website successfully but then it stopped working after about 2 days. The developers working on the site said that they did not change any settings.

The strange thing is I can verify that we are setting the memory limit well above the "allocated" amount specified above. I currently have it set to 128M and can verify this with phpinfo() on the root folder of the Drupal install.

http://transfer.itif.org/

http://transfer.itif.org/phpdata.php

Any ideas?

I have tried restoring the Drupal database, all Drupal files, clearing the cache and reinstalling Apache.

I have also tried manually setting the memory_limit in /sites/default/settings.php and in .htaccess. I am completely stumped why the allocated memory is not higher. (I am on a VPS with 1 GB memory available).

Any help would be appreciated. Thanks.

You seem to run out of memory at 19M.

What does the admin/reports/status page inside Drupal say about the PHP memory limit? If it says 128M then maybe the web server sets another limit.

How do I see the admin/reports/status page? Just browse to that location? I get the same type of out of memory.

Hmm... yes that is a problem.

Because the memory_limit can be set in 3 different places, in php.ini, in .htaccess per directory, and in drupal's settings.php at runtime, and the latter settings override the former, I wanted to know which settings Drupal finally gets.

Normally, if you haven't set a memory_limit in Drupal's settings.php file with an ini_set('memory_limit', 'xxM') line, then the one reported by a phpinfo() file inside Drupal's directory is the true one.

Anyway, try this in a checkmem.php file inside Drupal's directory and see at which point it crashes with an "out of memory" error.

ini_set('display_errors', 'On');
$new_mem_limit = '128M';
$old_mem_limit = ini_set('memory_limit', $new_mem_limit);
print 'Memory limit changed from '. $old_mem_limit .' to '. $new_mem_limit .'<br />';

$step = 1;
while(TRUE) {
  $chunk = str_repeat('0123456789', 1024*1024*$step++);
  print 'Memory usage: '. round(memory_get_usage()/(1024*1024)) . 'M<br />';
  unset($chunk);
}

That is the real test of how far your php memory can go.

When I run the script, this is the output I see:

Memory limit changed from 256M to 128M
Memory usage: 10M

Fatal error: Out of memory (allocated 262144) (tried to allocate 20971521 bytes) in /home/hostitif/public_html/checkmem.php on line 9

Yes, it definitely seems to be running out of memory. What could be a cause of this?

I've added the line:

RLimitMem 128000000

to the .htaccess file and this seems to have fixed the problem. Although I'm still not sure I understand the cause.

So, there was an apache limit.

Yeah seems out of memory issue. Try if this can help http://drupal.org/node/76156. Also check your hosting provider.

Yep, I've done all of those items. And as you can see in the phpinfo(), the system shows the memory is there, but Drupal doesn't.
