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 {

}
}
