DaB.,
Do you use the same replication script for enwiki and jawiki? A jawiki user is reporting data corruption issues with a jawiki pageID...
> SELECT * FROM jawiki_p.page WHERE page_id=588373; page_namespace=0 page_title=IntelMac
http://ja.wikipedia.org/w/query.php?what=revisions&pageids=588373&rv... ==> <title>Wikipedia:?????</title>
If this is a data corruption issue that was recently fixed, would it be possible to replay jawiki to fix the corrupted data? If so, do you have an estimate when that might be run?
