In my 15 years on the 320, I have seen some cracking PIO but never anything even remotely approaching that. Also, miraculously, the PF learns how to not PIO as soon as they transition from W/S escape into G/A and set Config 3. All points to something odd going on when Config Full.
The previous OEB for this was meant to be fixed with an ELAC software update. As one previous poster said - looks like it has come back to haunt us.
