Large Images >3mb Fatal error - Out of memory on save

Setup

VPS Dual Core, 4GB Ram
CENTOS 5.9 x86_64 with access to WHM 11.36.0 (build 21)
Drupal 6.26
PHP 5.3.8 (From Drupal Status Reports Page)
PHP memory limit 512M (From Drupal Status Reports Page)

PHP.INI
memory_limit = 512M
upload_max_filesize = 25M
post_max_size = 25M

Problem

Uploading a JPG image that is only 3.5mb, not using any progress bar just a bare bones drupal install. Upload starts and takes anywhere between 20 seconds and 60 seconds to get one of the following errors.

Error# 1 - Produced when clicking Upload
Create a node -> Click Browse on the cck image -> Upload -> I get a vanilla "An HTTP error 0 occured. /filefield/ahah/[node_type]/[cck_imagefield]/0

Error# 2 - Produced when clicking save instead of upload
Fatal error: Out of memory (allocated 60293120) (tried to allocate 16640 bytes) in /home/[name]/public_html/sites/all/modules/imageapi/imageapi_gd.module on line 59

What to look for

In my case the exact error message when clicking save was "Fatal error: Out of memory (allocated 60293120) (tried to allocate 16640 bytes)". Note that this indicates that only 57.5MB available (thanks to quicksketch for noticing this), so in other words the 512MB indicated in Drupal is not necessarily true.

Solution

I contacted my VPS hosting company for assistance, here is what they say they changed.

  • upload_max_filesize = 100M (from 20mb) - My hosting company claimed this may have helped, even though I don't see how that is possible with a 3.5MB image.
  • Setting in WHM panel >> PHP Configuration Editor. The limit was changed from 256 to 512 Mb - Note that this should NOT have fixed the problem since the 'hard cap seemed to be 57.5mb
  • "php.ini" - The custom php.ini in the website folder had been setup with 512M, however, my hosting company stated that they updated the server-wide PHP.ini but could not give me more information than this.

    The PHP.ini they uploaded was quite different than the quick/simple code you find online. Perhaps some servers require some of these additional lines.
