php upload_max_filesize ignored - unable to upload 5gb file

Question

I'm unable to upload files larger than roughly 2gb. The max upload/post values were previously set to 2500MB so I thought that was the problem.

First,

# php --version
PHP 5.3.3 (cli) 

I set upload_max_filesize and post_max_size as follows

# vi /etc/php.ini
post_max_size = 5500M
upload_max_filesize = 5500M
[write/quit vi]

Next,

# service httpd restart
Stopping httpd:                                            [  OK  ]
Starting httpd:                                            [  OK  ]

I then confirmed the new configuration with a phpinfo() script:

post_max_size   5500M   5500M
upload_max_filesize 5500M   5500M

I go back to my script to upload another large data file (~4GB), and am again told that the uploaded file exceeds value of upload_max_filesize.

So, I am at a loss. I am able to upload 2gb and smaller files no problem. I've restarted Apache, and don't know where to go from here.

Solution

This PHP-Change log

http://php.net/ChangeLog-5.php#5.6.0

states that, until PHP 5.6.0, file uploads were limited to 2 GB.

Exactly what operating system, distribution, etc.?

CentOS 6.5, Apache 2.2

It does and the file size limit matches what is in php.ini. The software (VIMP) is known to work just fine with very large files ( >5gb )

Testing with php -i may still give him the wrong file. It isn't uncommon to have a completely different config for the CLI vs the Apache module, or CGI.

I'm updating the correct file because if I change upload_max_filesize to 9999M, then restart apache, I see that reflected in phpinfo();

64 bit CentOS with 24gb RAM. Wondering if I have a 32-bit version of Apache installed now. How would I find that out?

$ file /usr/sbin/httpd /usr/sbin/httpd: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped

is there an error message in error_log?
