Hi all,
i’ve a strange problem: in my conf i use proxy for external requests for
mp3 download to our backends in this way:
location ^~ /tag/ {
client_body_timeout 180;
proxy_pass http://192.168.61.226:8888;
proxy_redirect default;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Org-host $host;
proxy_set_header X-Org-uri $request_uri;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass_header Server;
}
From 1 to 3% of the requests the backend servers sent to nginx more
bytes then nginx logs and serves. In this example the backend sends
9445489 bytes and from nginx logs i see only 1994793 bytes sent.
This is a sample log lines:
$IP ADDRESS - - [09/Nov/2009:01:21:20 +0100] “GET
/tag/10233569/Piu_di_un_giorno_in_.mp3 HTTP/1.1” 200 1994793 “”
“Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR
2.0.50727)” “-” 66.040
In every case the request_time is > 60 seconds (my nginx version is
0.6.39).
Unfortunately i’m unable to reproduce the problem by myself. Any idea of
how to reproduce it ?
Is it a good idea to upgrade to 0.7.63 version ?
Any suggestions are welcome. Thanks in advance.
Daniele
Should this problem be related to socket leak bug fixed in version
0.7.25 ?

It seems the same behavior, i serve big files and sometimes its seem to
be truncated (in the example above 1994793 bytes instead of 9445489).

No, unless you consider “related” to mean “both happen in real
life”.

Nothing forces clients to download full reply. Just hitting
“cancel” by user explains everything here, not even talking about
connectivity loss etc.

Looks like timeout writing to client. Try looking into error log,
it should have details.

It’s probably a good idea, but unlikely to resolve anything here
(as it looks like there is nothing to resolve…).
