Large files get to 100% and then hang when uploading

[JoshoB]

So I've been working on a website where large files don't get uploaded via the Ajax drag-and-drop thing. These are files in excess of 100 MB. I've tried uploading a file of 160 MB and one of 250 MB and neither of them work. The progress bar gets to 100% and then nothing happens. I let it stay there for a few minutes, but it never gets resolved. Large files just don't get uploaded to the server for some reason.

I've also tried the trick where initHTML5 is replaced by InitOldSchool in the javascript file for the uploader (i.e. InputfieldFile.js in wire/modules), but still no dice.

These are the settings on the server/PHP.ini:

extension=apc.so
session.save_path = "/tmp"

upload_max_filesize = 1024M
post_max_size = 1024M
max_execution_time = 36000
max_input_time = 36000
memory_limit = 2048M
always_populate_raw_post_data = -1
date.timezone = "Europe/Amsterdam"
mail.add_x_header = On
enable_dl = Off
disable_functions = show_source, system, shell_exec, passthru, exec, phpinfo, popen, proc_open

And .htaccess:

php_value upload_max_filesize 1024M
php_value post_max_size 1024M
php_value memory_limit 1024M
php_value max_execution_time 36000
php_value max_input_time 36000

And also this in .htaccess:

<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

I don't see what the problem could be. But perhaps I've been looking at this for so long I just don't see the answer.

If anyone around here can help, that would be grand! Thanks.

Debugger in Firefox gives this error when it hits 100%.

You need to take a look at the Network panel and view the reponse for the ajax upload script - it looks like a PHP error that is causing that unexpected character - probablt something about memory.

As you can see I was not able to fix this... Maybe you find some helpful informations in those posts though.

Thanks, but it doesn't give an error in the Network panel at all.

Yeah, I haven't had any luck with any of those solutions either.

Thanks anyway! I'm almost 100% sure it must be some server error, but I'll be damned if I know what?

Thanks everyone; I managed to solve it in the end. It was a stray line of PHP code where I redefined a variable that overrode my PHP.ini settings. A silly mistake, but one that proved to be very hard to track down.

Tracy can really help with reporting of image upload errors - usually you'll get warnings/notices in the the errors panel, or you'll get Tracy's "Buescreen" for fatal errors.
