Larger sites with greater than 100,000 objects may encounter issues during the sitemap building process with the default configuration, such as the process hanging around a specific number indefinitely or exiting the process entirely before completion. These users may want to try unchecking the "Prefetch URL aliases during sitemap generation" option found on the xmlsitemap admin configuration page (/admin/config/search/xmlsitemap/settings) and trying the process again.
