> We found some PageCursorInfo in consumedPage map even if these corresponding
> page file is deleted.
> Suppose that there is a topic t with some messages not routed to subscriber
> ta. When calling ta.deliverAsync(),
> DeliverRunner->deliver->checkDepage->pageIterator.hasNext->
> processACK->cleanup is called in the pageSubscription's executor(step1), then
> checkDepage->pageIterator.hasNext->processACK->getPageInfo is called(step2).
> At this time(step2) pageCursorInfo maybe again put into consumedPage when the
> page is removed from consumedPage but not from softCache(int step1).
