Project Description:
We are having a strange issue on our site http://uberhumor.com. The internal post pages like this http://uberhumor.com/so-glad-that-this-fashion-magazines-celebrate-all-body-types do not load sometimes and it appears blank but when you refresh the page loads just fine.

The server is running on Nginx with super cache enabled on Wordpress on a CentOS server.

Some of the errors we are seeing in the PHP log are as follows..

Feb 26 15:25:37.359349 [NOTICE] fpm_got_signal(), line 48: received SIGCHLD
Feb 26 15:25:37.359426 [NOTICE] fpm_children_bury(), line 215: child 20401 (pool default) exited with code 0 after 826.432198 seconds from start

When we give a new link to a post to Facebook, the Facebook crawler is not getting those details either. It shows like this https://www.facebook.com/permalink.php?story_fbid=357222671058702&id=153721174785449 instead of showing all the info like this https://www.facebook.com/uberhumor/posts/606815542678482
