Steps to reproduce

I created a branching exercise, with approximately 32 videos, and 50 steps in total.

The 32 videos are around 900mb in total.

The server had 6gb available.

When I load the exercise, the hvp in data/temp duplicates itself several times until the disk is filled.

I created another 20gb volume and moved moodle onto that, and now the 20gb volume is full.

Curious if you have found any solution to this problem?

We are currently experiencing the same issue - it has crashed our Moodle environment a few times this week and as more and more usage is pushed to the online environment, the problem has gotten worse.

I did find a solution - rather than using videos on the moodle server itself, I linked them from vimeo using distribution links.

Hi All,

I tried to reproduce the issue but I am unable to do so. By design a duplicate of the content/files are created when exporting but this should only create 1 duplicate. If anyone in the community have any ideas on how to isolate the issue feel free to post your comments.

We are also experiencing the same issue in a Drupal environment (7.x-1.46).  Temp directory gets filled as soon as the node is accessed until all available space is filled (70GB).  There are a few interactive videos within the branching content type
