Broken downloads (digital delivery)

I set up a shop and it appeared to function properly.
When I tested it, I was able to download file (digital delivery) with no issues.

However, not everyone is that lucky. I'd say 70% of my customers either download ~370Mb of the file (~412Mb is the correct size) or if they download it at all, after so many attempts, they get corrupted archive.

I spoke to my hosting admin and he said there is nothing wrong on his end.

Has anyone had that issue? How can I fix the issue?

Thank you.

Thanks.

Maybe a timing out or max post size issue with the webhost config, try this

Just set one up and test it. You might check your server error logs and Zen Carts debug logs for some clues as well.

Apache logs contain no errors, neither do broken downloads :/
Where can I find Zen Carts debug logs ?

EDIT: There is nothing that I don't know on that Wiki page you linked me to :)

How do I raise a timing out value and max post size value?

In your cache folder

Hmm..

You server's PHP config failed to deliver the download as it timed out due to execution time.

Your webhost *might take care of this for you. If you are on a shared server with no ini file, then they will not increase for the whole server just for you.

A 412 Mbs file size is substantial, especially if more than one person at a time are downloading it. The download may be passed off to Apache to handle and this can tie up an enormous amount of Apache resources on the whole server - slowing down delivery of other people's sites on the same server.

You need either a VPS or full Dedicated Server for downloads of that size. Shared Hosting is not suitable.
