I'd say you need to report this to AWS support - we have no idea what
changes they made in Aurora, and AFAIK they made a lot of changes in
this area.
That is not to say we don't have any bugs in this area - see for example
the discussion in [1], but we are not in position to investigate issues
on a proprietary product.
