I started that wiki with version 1.38 as a fresh installation, then upgraded to 1.39, Then the update script started some very long time tasks on some tables (i don't remember their names) after the upgrade.
The wiki remains online and everything is working for now, except for the same reported error that appears when running the update.php.
