Googlebot found an extremely high number of URLs on your site: Pdaapps

Code:
Googlebot encountered problems while crawling your site http://www.pdaapps.org/.

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.
