Everyone was researching... I was taking little comments made by various people in chat and then checked out what I could on github... coming back, etc, etc... examining my own witness node, and my own source code I had available. (I don't run docker images).
I by no means should take credit for finding the problem. We have everyone in the private slack who did all of it... and they deserve the true credit.
I am simply reporting what I found out, and verified to be true.
