After some discussion with DBAs going to pause the migration script and try rolling forward ro reads for Q6 million and see how it behaves. If we see the same issue, then we may have to continue investigation. If we don't see the same issue, then perhaps we already need to start reducing the batch size and increase the sleep for the migration while we have more reads. I'm also generating SQL based lists for all remaining batches of holes (NOte, this will only make sense for items that have already been migrated due to the query being used.. https://phabricator.wikimedia.org/P10537 ) In order to see what needs to be migrated post Q50 million I might have to come up with a query against the page table..
