Good morning Alex,
thank you for your insight. I will test it as recommanded and using version 1.0 just realeased.
I am using the recommanded docker version, meaning Docker version 1.11.2, build b9f10c9.
I will start from the scatch again with debug on and the new docker client timeout.
Let's see how it works out.
cheers and keep you informed,
Stefano
