Strange IP on PTP400

We have a PTP400 that has reverted to an IP address of which seems to have happened during a storm.

The BH is still connected to the other side of the backhaul and is passing data. We tried reverting to recovery and upgrading it back to the firmware it was on 09-02 but it still went back to

Has anyone seen anything like this?

i have this issue happening right now on a legacy spur link.  I am curious how, if at all, you were able to resolve it.
