Hi,

just my $0.02 so to say:

sounds to me as if a b-tree is in a perculiar state and that updating the
btree results in this corruption.

Have you tried to mount one of the checkpoints/snapshots earlier as RO and see
if those are correct? If so, dumping both DATs and both btrees might give a
clue as to what went wrong. If only it gives a clue as to how complicated the
btree is before the updating and what actions are taken on it.

With regards,
Reinoud
