if you are running Stellar Express cluster in production, first of all you have to make a listing of all MAC-OUI of your AP1101s.
upgrade from 3.0.2 to 3.0.3 is a major upgrade that could make possible database corruption with old AP1101 MAC-OUI.

Hi Morne,
I have only used express mode a handful of times but I found upgrading the AP’s through express pretty aggravating.
Try upgrading one at a time if this is still occuring I would contact TAC as there could be a deeper lying issue with the code.

I also assume this cluster is in a production environment?
