I don't think MediaWiki manages SQLite lock and concurrency at all. In this case, it seems two different Apache PHP threads are attempting to update the message cache. For CI purposes, maybe we want to repopulate the message cache in the DB or skip it entirely to use the good old messages PHP files.
