[William Attwood]

Upgraded to APC 3.1.13.  No change, still segfaulting.  Upgraded to latest kernal:

However, it is not including a different file.  Some are still nap.ctp, while others are social.ctp.  Each one is when a function is defined:
[0x7fc6d7601e50] ??? /.../social.ctp:58 
[0x7fc6d7600dd8] ??? /.../view.php:1159 

social.ctp:58
57: if(!function_exists('iconCreate')){
58:        function iconCreate($imgName, $iconClass, $icon_set, $icon_set_path){


Also, this appears to happen most at 1:30-1:40AM server time, and the servers impacted are random between WEB13 and WEB27.   With some sporadic segfaults during the day.
