Running an old file manager program, which is written in PHP and runs on PHP server 5.2.11, and all running on IIS 6.0 (Windows 2003). It seems this file manager gives an HTTP 500 error when downloading files roughly 32MB or larger, but doesn't on anything smaller. I cannot find anything on the internet about it, and its hindering our customer support, so really need an answer.
Without knowing much more, is there a known issue about this?? I can pass along any info you need, but really need help on what to look for. It is not a timeout issue (I don't think), as the website timeout settings are set high and the error pops up just as quick as a file that actually downloads.
And I don't know enough to know if its a website issue with IIS, or the PHP code for that file manager application. Didn't know if it has something to do with the application pools or something in IIS or whatever, I am just grabbing at anything now. But basically we post a PDF that's 31MB and a PDF that's 33MB (or any size difference in between). If the user clicks the 31MB file, boom it pops up asking to save or open. If they click the 33MB file, boom it flips pages to the HTTP 500 error.
