Note as well, reason I have two configuration types listed is just to experiment with various methods for the best Requests/Second for php.. one using a single fast-cgi php-cgi process (which seemed to crash a Lot when sent a huge amount of request as demonstrated by using ab, although nginx itself remained stable) the other using proxy_pass for a apache mod_php only for dynamic content which seemed to be much more stable and handled the request.
Only when setting the cache directives for either the fastcgi or proxy method did I incur the immediate crashes.
