Hi,

I have a problem today with one of my servers that are handing a live streaming app.

The error log look like this :

2016/10/16 16:50:38 [alert] 4418#0: *98869 pread() read only 0 of 32768 from "/mnt/ID/720/7200.ts" while sending response to client, client: xxx.xxx.xxx.xxx, server: nginx04, request: "GET /ID/720/7200.ts HTTP/1.1", host: "nginx04", referrer: "https://xxxxx.xx"

I found that some people say that i have to disable open_file_cache, but if i read the manual of nginx this option is disable default.
But in my nginx.conf i dont have the line at all, so are the open_file_cache enable if there is just nothing in my nginx.conf file that are contains open_file_cache?

I using a own compile version of nginx version :
nginx/1.8.1

Kind regards

Maybe the default is 'on'

Syntax: open_file_cache off;
open_file_cache max=N [inactive=time];
Default: open_file_cache off;
Context: http, server, location

Default is off so somewhere you must have enabled it, or just force it off.

There might be other OS situations/configurations that do such things beneath nginx which causes the same thing.

How can i see if it on? I have search for grep -r "open_file_cache" . inside my nginx config folder and there is no hit at all.

Is there any option to get a print of the running configuration live ?

That command is not working out well!

nginx -T
nginx: invalid option: "T"

Options:
-?,-h : this help
-v : show version and exit
-V : show version and configure options then exit
-t : test configuration and exit
-T : test configuration, dump it and exit

1.8 is pretty old.
