More items scheduled for publication than in queue for publisher
This alert means that the number of editions in the publisher database which are scheduled to be published in the future is different from the number currently in the Sidekiq queue.
This can happen in Staging and Integration as a result of the data sync from Production. Run this rake task to re-queue all scheduled editions:
$ cd /var/apps/publisher $ sudo -u deploy govuk_setenv publisher bundle exec rake editions:requeue_scheduled_for_publishing
