Wanted to circle back on this as it is seems we have resolved our issue.
None of the application level changes related to content downloading on slow or unreliable connections worked.
We had some boundaries that were present but unassigned to a boundary group. Due to the nature of the error we previously had, we deleted all of the unassigned boundaries and haven't seen the issue since and have had 100% success on our OSD builds since cleaning them up.
We had done this type of cleanup in the past, but these were left for some unknown reason.
We don't fully understand why the errors trended up so quickly as the unassigned boundaries were there for quite sometime without any ill effects.
Thinking it was a random issue related to the MP_Location mechanism.
