2014-06-19 20:03:57 mw1007 enwiki: Update for doc ids: 38124800,38124800; error message was: Error in one or more bulk request actions:
update: /enwiki_content_1401733677/page/38124800 caused VersionConflictEngineException[[enwiki_content_1401733677] [page]: version conflict, current , provided ]
Why in the world are we trying to update the same page twice? Of course it isn't going to work! Elasticsearch will update the page once and then quickly try again and get a version conflict with the update it just did!
