First, we created a simple page that spit out phpinfo(). Note that it is important that you run this thru the web server – running php -i DOES NOT include any overrides that apache may add.

Removing those values from php.conf fixed the problem.
#php_value session.save_handler “files”
#php_value session.save_path “/var/lib/php/session”
