I received an email from Google saying one of my site may have similar or identical pages.

Here is the message

Googlebot encountered extremely large numbers of links on your site. This may indicate a problem with your site's URL structure. Googlebot may unnecessarily be crawling a large number of distinct URLs that point to identical or similar content, or crawling parts of your site that are not intended to be crawled by Googlebot. As a result Googlebot may consume much more bandwidth than necessary, or may be unable to completely index all of the content on your site.

The urls that Google bot found are

http://www.example.com/videos/p/2
http://www.example.com/news/p/237
.....
......

On paginated pages I am using <link rel="canonical" href="http://www.example.com/news" /> and the Firefox extension detects it fine.

Wondering if I am doing anything wrong?
