Hi!

I am using nginx 1.2.4 (from ALT Linux Sisyphus package nginx-1.2.4-alt1). Simple:

kill -s USR1 PID

don't work. nginx don't reopen new access.log as it should.

To reproduce:

nginx.conf excerpt:

location /tmp/ {

alias /tmp/; autoindex on; dav_methods PUT;

}

location /test/ {

proxy_pass ​http://localhost:8000; proxy_set_header X-Real-IP $remote_addr; proxy_pass_request_body off; proxy_set_header Content-Length 0;

}

on a console: socat TCP-LISTEN:8000,reuseaddr,crlf stdio

chrome console: var xhr = new XMLHttpRequest() xhr.open("put", "​http://<scrubbed>/test/1234") xhr.send("fubar")

socat: PUT /test/1234 HTTP/1.0 X-Real-IP: <scrubbed> Content-Length: 0 Host: localhost:8000 Connection: close Cache-Control: no-cache Pragma: no-cache Origin: ​http://<scrubbed> User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.57 Safari/537.17 Content-Type: application/xml Accept: */* Referer: ​http://<scrubbed>/ Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3

HTTP/1.0 200 X-Accel-Redirect: /tmp/asdf

nginx/error.log:

2013/02/13 20:08:12 [error] 1494#0: *12474 open() "/tmp/asdf" failed (2: No such file or directory), client: 192.168.8.189, server: , request: "PUT /test/1234 HTTP/1.1", upstream: "​http://127.0.0.1:8000/test/1234", host: "<scrubbed>, referrer: "<scrubbed>"

If I try to do a PUT request directly, it creates the file...

Dear All,

This week we received a lot of segmentation fault. I debugged and you can see below my gdb examine.

(gdb) p pc->sockaddr $1 = (struct sockaddr *) 0x0

I think peer connection sockaddr is null.

Thanks.

Kind Regards
