Provisioning "Fails" IP Address and DNS Name have been taken

Provisioning "Fails" IP Address and DNS Name have been taken Chris 11/2/15 9:13 AM
I have a new implementation of Foreman 1.9.2 and I am running the 1.9 Windows Smart-Proxy on my 2012R2 DHCP server. When I provision a host everything goes as expected until Foreman is waiting for the host to become available. During this part of provisioning I get a "failure" that tells me in the Interface configuration the DNS name and IP Address have already been taken. The strange thing is the server build and configuration still goes as expected and if I look at the all hosts page the new host is there in good status.

Foreman 1.9.2
Foreman Windows DHCP Smart-Proxy 1.9.2
Windows Server 2012R2 (DHCP)
CentOS 6.7 (Foreman)
Foreman Memcache Plugin


Any assistance would be greatly appreciated. There is nothing in the production.log or the proxy.log that show any errors and I have both set to debug.

Sorry for the slow reply Chris - just an idle thought, is this in the UI or API?

I occaisonally get issues with my setup where editing a Host and
saving it again leads me to the Overwrite confirmation (which looks
remarkably like a fail, the Overwrite button is red). In the API iirc
it auto-fails such conflicts, as there's no interactive element that
can ask for confirmation of an overwrite. I've never gotten around to
debugging my setup, since if I accept the overwrite it's generally
fine.

No worries. I am provisioning through the webUI. I have to do some more digging but when I have the developer tools on using firefox i do see a bunch of these errors around the time the error happens http://pastebin.com/4PNuGd9V. I can also see a duplicate post command in the logs trying to build the host again. It's very strange since I haven't seen this before in my lab environment which is heavily used.

Ooh, a duplicate POST sounds very odd, and not what I was referring
to, indeed. I wonder what's causing that?
