I am a coworker of David's and wanted to follow up to see if anyone has experienced similar issues. A little further explanation:

Not every upload the instructor is making takes so long or times out. Usually it happens during a session where the instructor needs to upload multiple files at once, and normally after one or two uploads have completed quickly--as expected. We have exhausted every basic troubleshooting route and can see the PHP requests being made from our server and then simply not completing. Starting the upload back over again usually resolves the problem, but for large classes this can be a time consuming process for the instructors.

Is it possible that it is just an issue with Moodle's file handling process? Is there anything we can change in our environment to hopefully improve the issues we are encountering?

Thank you,

Colin

I had the same issue, my workaround was by setting up a repository in moodle and dropping the files into the folder on the server, that way you can just select from the uploader and because the files are already on the server...no waiting
