If you read previous threads, this is the #1 broken feature request right now for
researchers and other people interested in full dumps.
The dump process have been broken now for more than a whole year, and admins are
overwhelmed with urgent work, so it seems it will still take a long while to repair it
again.
Other editions are starting to fail in the same black hole too, as the grow in size.
Bests,
Felipe.
