I have a website that offer downloads of some large files, up to 10gb.

There is an issue with the downloads that doesn't happen to me, and actually doesn't happen to most of my users, but I keep getting messages from some users that their downloads stop at 2gb, and the file is larger that that.

I serve the downloads using nginx XSendfile with php:

header('X-Accel-Cache-Control: no-store, no-cache, must-revalidate');
header('Pragma: no-cache');
header('Content-Type: application/octet-stream');
header('Content-Length: ' . $this->getFileSize() );
header('Content-Disposition: attachment; filename="' . $fileName . '"');
header('Accept-Ranges: bytes');
header('X-Accel-Buffering: yes');
header('X-Accel-Redirect: ' . $this->getServeDownloadLocation());

Running on CentOS 6.6, php 5.5.22, nginx 1.6.2.

Notice: the users don't use old browsers, they use modern browsers like Google Chrome.

Can you post your php.ini file? – C.Liddell Mar 13 '16 at 01:58

Perhaps they're downloading to FAT filesystems. – Lori Mar 13 '16 at 02:45
@Lori I have spoken to one of them, he told me he is downloading to NTFS file system, and also mentioned that the problem happens to him only sometimes, and not always. – HTMHell Mar 13 '16 at 11:17
Check your nginx log, is `$body_bytes_sent` always at 2Gb? Also check the `$request_time` to see whether there are any trends. – Tan Hong Tat Mar 14 '16 at 05:19
