MediaWiki:Smw-category-change-propagation-locked-error

Category '$1' was altered and requires assigned entities to be reevaluated using a change propagation process. In the meantime, the category page has been locked until the primary specification update is completed to prevent intermediary interruptions or contradictory specifications. The process may take moment before the page can be unlocked as it depends on the size and frequency of the job queue scheduler.
