I am seeing this too but nowhere as frequently as you are. I hit this
last night for the first time and not since.

There hasn't been any change in this part of the code for quite some time now.

Since you can trigger this much more frequently that me, would it be
possible for you to narrow down which change caused this? It would be
hugely helpful.
