I'm having difficulties uploading large (~250MB-1.9GB) SCORM files to my Moodle (2.4.1-weekly on a 6GB Linux VPS).
It appears to be successfully uploading the SCORM file, through the file picker. This was the first hurdle I overcame - by tweaking the PHP settings, e.g. upload_max_filesize, etc.
The problem occurs when I get to the final "Save and Return" button. It spends 1-2 mins loading/processing/thinking about it, but finally ends up returning an "Error: zero-sized reply" message.
This issue affects all the large (~200MB+) SCORMs I have, including from different producers. SCORMs smaller than 150MB have been successfully installed, including on the most recent Moodle 2.4.1+.
I've been trying to debug this for so long I cannot see the wood for the trees anymore. It's an issue that gets raised again and again on the forum, but never properly answered.
Does anyone know the reason for this problem, or have any helpful suggestions?
