Description
Easily reproducible:
Follow the instructions as detailed here: A single HTTP/HTTPS server
Then request https://127.0.0.1
Nginx stops working because the socket is blocked, if you stops the page loading then Nginx starts working again.
I took a trace with api monitor in windows XP, it is as follow:
nginx.exe WSASetLastError ( ERROR_SUCCESS )
|
nginx.exe WSASetLastError ( ERROR_SUCCESS )
|
nginx.exe recv ( 296, 0x0189695b, 16709, 0 ) 37
|
nginx.exe WSASetLastError ( ERROR_SUCCESS )
|
nginx.exe recv ( 296, 0x0189695b, 16709, 0 ) SOCKET_ERROR 10035 = No se puede completar de forma inmediata una operación de desbloqueo de socket.

nginx.exe WSAGetLastError ( ) WSAEWOULDBLOCK
|

|
nginx.exe recv ( 296, 0x0189695b, 16709, 0 ) 1061
|
nginx.exe ioctlsocket ( 296, FIONREAD, 0x01a6ff18 ) 0

nginx.exe WSASetLastError ( ERROR_SUCCESS )

|
nginx.exe WSASetLastError ( ERROR_SUCCESS )
|
nginx.exe send ( 296, 0x0188f90b, 213, 0 ) 213
|
So I added a couple of DPRINTs in recv() to see what's happening:

if (Status == ERROR_SUCCESS)

|
if (!(flags & MSG_PARTIAL)) return BytesReceived;
|
ErrorCode = WSAEMSGSIZE;

}

This patch leads to this log:
(/dll/win32/ws2_32/src/recv.c:34) recv: 76c, 2, 1, 00ABFEF4

|
(/dll/win32/ws2_32/src/recv.c:34) recv: 76c, 0, 4145, 0093BFB3
|
Then it stops until either I stop page loading in browser, or kill nginx.exe. In both cases we never reach the send() call.
