Sorry to hear that no one in this community was able to offer
any suggestions.
But it appears you are much more equipped with this advanced
topic.
By the way, CF Admin indicates the parameter as being a
buffer and not a
byte limit, although it is probably one in the same in this
context.
Did you also have to enable binary large object retrieval?
Anyway, I would rather see this label changed to something
like...
Blob: max size in bytes
Good find and thank you for posting the solution.
