Nginx http-bind eJabbered pending requests Chrome

[soisita]

Hi,
I'm working on a server where nginx runs as proxy on Apache
It proxies php files & ejabbered requests & serves static files

Everything was fine until a few weeks, and only on Chrome:
when http-bind is pending, it makes all further requests pending also, thus
all images called after the http-bind request are "pending" until ejabbered
answers (about 1.5 min)

Any idea?

here part of the conf:
nginx/0.7.67

user www-data;
worker_processes  8;
worker_cpu_affinity 0001 0010 0011 0100 0101 0110 0111 1000;

error_log  /var/log/nginx/error.log;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
    multi_accept on;
}

http {

    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;
