Nginx http-bind eJabbered pending requests Chrome

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;
sendfile        on;
tcp_nopush     on;
server_tokens off;
server_names_hash_bucket_size 128;

#keepalive_timeout  0;
keepalive_timeout  65;
tcp_nodelay        on;

add_header Access-Control-Allow-Origin *;

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;

}

site:
server {
bla bla
location /http-bind/ {
tcp_nodelay on;
keepalive_timeout 55;
proxy_pass http://chatdomain:5280/http-bind/;
}
}

server {

server_name STATICSDOMAIN;

    # redirect server error pages to the static page /50x.html
    #
    #error_page   500 502 503 504  /50x.html;
    location = /50x.html {
            root   /var/www/nginx-default;
    }

    location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|srt|swf|pdf)$ {
            root  /PATHTOSTATICS;
            expires           30d;
    }

}
