Page is a not externally linkable

The big SE spiders undoubtedly have certain criteria they use to determine whether or not to stop adding links to their crawl list from a given site but I'd be willing to bet none of them have a specific numerical limit.
500 links is nothing. I wouldn't worry. A lot of dynamically generated sites have far more internal links than that. And many directories have far more external.
