Description

How to reproduce:

  1. Create a 10GB data file.
  2. Download from localhost:
$> wget -O /dev/null --report-speed=bits localhost/10G.dat -t1
--2020-01-14 15:54:11--  http://localhost/10G.dat
Resolving localhost (localhost)... 127.0.0.1
Connecting to localhost (localhost)|127.0.0.1|:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: 10737418240 (10G) [application/octet-stream]
Saving to: ‘/dev/null’

/dev/null            40%[======>            ]   4.00G  --.-KB/s    in 64s     

2020-01-14 15:55:16 (535 Mb/s) - Connection closed at byte 4295060433. Giving up.

Expected result: the file is downloaded.

Actual result: the download stalls at an even number of gigabytes (2, 4, 6, 8...). In the example, at 4 GB + 93137 bytes.

Reproduced in Nginx 1.14 and 1.10.3.

This looks like duplicate of #1870. Consider configuring sendfile_max_chunk.
