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 TLS SNI support enabled configure arguments: --with-cc=cl --builddir=objs.msvc8 --with-debug --prefix= --conf-path=conf/nginx.conf --pid-path=logs/nginx.pid --http-log-path=logs/access.log --error-log-path=logs/error.log --sbin-path=nginx.exe --http-client-body-temp-path=temp/client_body_temp --http-proxy-temp-path=temp/proxy_temp --http-fastcgi-temp-path=temp/fastcgi_temp --http-scgi-temp-path=temp/scgi_temp --http-uwsgi-temp-path=temp/uwsgi_temp --with-cc-opt=-DFD_SETSIZE=1024 --with-pcre=objs.msvc8/lib/pcre-8.32 --with-zlib=objs.msvc8/lib/zlib-1.2.7 --with-select_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_stub_status_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-mail --with-openssl=objs.msvc8/lib/openssl-1.0.1e --with-openssl-opt=enable-tlsext --with-http_ssl_module --with-mail_ssl_module --with-ipv6"
