CPE already in session

Hey there,

On my path to get 1.2.7 working, I got the logs below on the cwmp service.

CPE already in session

After that, I cant get any information from the device, and after rebooting, the problem persists.
Is there anything that I can do? What`s the reason for that?

Note: Just to clarify, the device sends info to the ACS, but the server responds with the log above.

It was possible to replicate the problem, by sending REBOOT to the device through the ACS UI Interface.
