 * I am getting periodic high CPU loads from my WP site – on occasion enough to 
   crash the site. I have a Linux VPS so resources should be ok. The logs indicate
   index.php as the culprit and I’ve tried disabling plugins and it seems that W3Tc
   is the one causing the high CPU load.
 * Hoping there’s a setting somewhere that can fix this as site performance has 
   improved dramatically with W3TC installed.
 * Thanks
