Do not add your post to a thread that's over two years old and please provide more information about your specific problem when posting. I'll move this to a new thread and please change the title of this thread to something more appropriate to your problem description.

Your hosts file is incorrect and your resolv.conf should only have one DNS server in it (that's the one you have on your LAN). Go to the Split DNS article and read the 'Verify...' section of that article to verify your configuration. When you've done that and fixed the errors you should also disable memcached (details in the forums) as it's not required on a single server installation and shouldn't be enabled. You can also check in the log files to see what errors you get.
