Hi All,

I am using nginx server. On user's request, I am creating a file and providing a download link for that file. The file size is 2.1 GB. I am observing that when we click on that link, only a part of that file gets downloaded which varies at different occasions. Can you guys help me on this as I am stuck at that point. Thanks in advance.

I am running nginx/1.0.14. I have been trying to download a tar file, which is of the size 2.0 GB. But it is downloading only a part of it. The downloaded part varies on different occasions.
The output of nginx -V is as follow -

nginx version: nginx/1.0.14

Also, Below I am providing error_log corresponding to this download event ----

Thanks.
