File download fails every time
I'm trying to sell files on my website. Everything is set up, but when the user comes to download the file, the server kills the connection after a period of time. Sometimes the download gets to 20% sometimes 50% depending on the download rate but the connection always dies before the file finishes.
I've tried doing the download with DownThemAll and it comes up with a "Size mismatch" error when the download dies. I've looked at the logs and they say that a stop request has been received.
I've tested commerce with a small zip file and the download completes without trouble. My file is 118MB. Is it possible that there is some Apache setting which is interacting with the way that Commerce serves the file which causes the download to be cancelled after a certain period of time?
This issue is very frustrating so any help would be greatly appreciated.
