"Mitigated" as in, it goes away entirely, or is less likely to occur, or
... ?

Do you mean u9? "between u8 and u9" I would take to mean that the issue
does not exist on u8, so... Or do you mean it happens on u8 only when
you've applied certain patches?

Do you know what the cache size and chunk size was in these situations?
(You can get these from 'cmdebug -cache', in the future)
