First, there is no such module by default.
Anyway, if you are using the free one which shows all pages in 14 page then its the problem caused because of your news. You have 149602 news in your database.
There are too much news in the database to show up in 1 page.
Try changing server as you need a server with good memory.
Or edit the free module to show sitemap page by page too.

Edit: you have posted in wrong Section.
It should be in Technical Help Desk Support section.
