This is not exactly php list and not really related to nginx, but you should 
start by at least telling your php version, there have been a bunch of bugs 
fixed regarding fpm and cpu hogging (also in php core itself) in past.

It can always be a poor php code (<? while(true) { } ?>) though but without 
the fpm backtrace it's hard to tell.
