There seems to be a problem with Debian distributions (tested for both Wheezy and Squeeze) using Odoo for longpolling port. longpolling port is never used. It supposed to be used wen `workers` parameter is set to be greater than `0`, but it is not used anyway. But testing same thing on Ubuntu, longpolling port is used normally.

There is an original Question (last comment of the issue) <https://github.com/odoo/odoo/issues/3793>

checking nginx log I see this (everytime it tries to access longpolling through reverse proxy):

```
2015/05/08 07:54:09 [error] 32494#0: *8 connect() failed (111: Connection refused) while connecting to upstream, client: IP address, server: _, request: "POST /longpolling/poll HTTP/1.1", upstream: "http://127.0.0.1:8072/longpolling/poll", host: "db.host.eu", referrer: "http://db.host.eu/web"

```

And when I try to connect to `8072` port via telnet:

```
$ telnet 127.0.0.1 8072
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused

```

But trying for example:

```
$ telnet 127.0.0.1 8069
Trying 127.0.0.1...
Connected to 127.0.0.1.

```

So it seems that 8072 port is not used?
In my odoo config it is set to be like this:

```
longpolling_port = 8072
xmlrpc_port = 8069
workers = 2
xmlrpc_interface = 127.0.0.1
netrpc_interface = 127.0.0.1

```
