362	deadlock on win32 with accept_mutex and multiple worker_processes	Ogurets Aggressive		"To reproduce an error following things are required (all of them):
1. worker_processes > 1
2. accept_mutex on
3. server record like this:

{{{
    server {
        listen       80;
        server_name  localhost;
	location / {
            proxy_pass          http://SOME_IP;
            proxy_buffering     off;
        }
    }
}}}
Where ""SOME_IP"" is an address of another server (not sure if it matters though).

Accessing this location from a browser stucks in ""waiting for answer"" for a very long time.
Following workarounds seem to solve the problem:
1. Set ""worker_processes"" to 1
or
2. Set ""accept_mutex"" to ""off""

Also, non-proxy locations (without ""proxy-pass"") seem to work fine under the same conditions, only ""proxies"" are affected."	defect	closed	minor		nginx-module		fixed	win32 worker_processes accept_mutex deadlock		Microsoft Windows [Version 5.2.3790] (Windows 2003 Server SP2 Enterprise x64)	"nginx version: nginx/1.4.1
