However at apparently random times we do still see errors being reported, its not consistent at all. To give a better idea of the problem we have 8 web servers, they all run an identical copy of the site which is stored on a common netapp nfs filer. At apparently random times we see that 1 out of 8 servers will reported strange errors like 'use of undefined constant' or 'Undefined variable'. What's most strange about these errors is that if the code was faulty wouldn't we expect to see the errors on all web servers? and secondly wouldn't we expect to see the errors constantly rather than at apparently random intervals?

Sounds like someone added either ini_set('display_errors','On') in
the script being called or an include, added a local php.ini file to
the directory (or a parent directory), or added a php_flag to
.htaccess in the directory (or a parent). Try checking into those
possibilities.
