Empty Sitemap

Hi,



When i try to submit sitemap to Google its gives me a error,

Empty Sitemap - Your Sitemap does not contain any URLs. Please validate and resubmit your Sitemap.

But when i click sitemap url its shows me 1598 url, when i submit the same url to Google gives me the above error message,

This is first time i am facing this kind of problem with Google & Xmap,

Any one can help me on this
