With a business license you are able to crawl 25.000 URL's. Customer Kees Smit (12584) noticed it stayed at 0% after they started and restarted their crawl. In the backend we saw they were not able to crawl more than 10.000 (limit). Customer Bemmel&Kroon (17096) might have the same issue as they mentioned they couldn't crawl more than 10.000 URL's. Workaround > no limit on crawls for the customer. Once the bug is fixed we can reset this to their standard crawl limit.
