I get this msg in my google webmaster tools area regarding my sitemap:
Web crawl errors
HTTP errors 0 --
Not found 11788 Details »
URLs not followed 9 Details »
URLs restricted by robots.txt 0 --
URLs timed out 0 --
Unreachable URLs 13 Details »
When I go into the (Not found) page it lists all links that where not found. I click on one of the links at random, When I click the link the link is dead.

Why the aitemap crawling old pages deleted from my site? Can this be the prob??
