У меня проблема не устранилась. Игрался с процессорам и коннекшинами, не помогло.

Вот мой конфиг:

worker_processes 2;

error_log logs/nginx_error.log;
events {
worker_connections 1024;
}


http {
include mime.types;
default_type application/octet-stream;

sendfile on;
keepalive_timeout 0;

server {
listen 80;
server_name localhost;

error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}

location ~* \.(jpg|jpeg|gif|png|ico|css|bmp|swf|js|html)$ {
root /Server/gora;
}

location / {
proxy_pass http://localhost:82;
proxy_redirect off;

proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
}
