'Pathauto' comes with a bulk update feature that is supposed to be able to bulk update (create) taxonomy term aliases. However, this does not work for me on a site with approximately 35,000 taxonomy terms.
The setting is available at
./admin/build/path/update_bulk, I can start the procedure, and the batch API claims to initialize. Thas goes on for at least an hour, without any errors or timeouts. Nothing related to path aliases is logged in Drupal's watchdog, Apache's error log remains clean of new error messages, as well. As far as I can tell, no aliases are created at all. It just "initializes" (screenshot attched), but seems not to do anything.
Any workarounds or other suggestions how to fix missing aliases?
