Just installed v10 for the first time (from github) and am having an issue.

Starts fine when workers = 0 but as soon as I change to Workers>0 (workers=4) I get this:

2017-10-25 18:40:05,773 30368 INFO ? odoo: database: odoo10_0@127.0.0.1:5432 2017-10-25 18:40:05,777 30368 INFO ? odoo.service.server: HTTP service (werkzeug) running on 0.0.0.0:8069 Traceback (most recent call last):

    self.socket.bind(self.address)
 File "<string>", line 1, in bind socket.error: [Errno 98] Address already in use

But sudo netstat -an | grep LISTEN does not show any other processes on port 8069 or 8072.

I have tried changing the xmlrpc port and the longpolling port in the config file too but I still get the same error.

Any ideas appreciated, thanks.
