Downloads are intermittently giving errors. After the user successfully checks out, they click on the link to the download the file, then they go to save the file on their computer and about 25% of the time they get a "file not found" error. I need help troubleshooting and fixing the problem. I know that osCommerce handles downloadable products by temporarily copying files from the "downloads" folder into the "pub" folder. Possibly, the file is big enough (600K) that the server can't copy the file over fast enough for the user to download it?
