Hi Rocco,
We will have to look to recreate this internally. In the meantime, can you please capture the CNUT debug info for the SMs that have shown this problem both when they are in the state as well as after they are recovered by manually pushing the reconnect button? We have a thorough PPPoE log in place that we can analyze to see where it is getting stuck.
You can send that to me on here via private IM.
Thanks,
Aaron
