apc issues

hi george/dan apologies for the direct email, perhaps you have some ideas regarding an APC issue that's come up. I have some fairly simple classes with only one level of inheritance, they work fine in a default PHP install but as soon as I enable the latest APC 2.0 extension i get an error reported that doesn't exist. PHP 4.3.3 APC 2.0 (public release) Red Hat Enterprise Linux ES release 3 (Taroon) Apache/1.3.29 (Unix) the include process is like this: 1. simple class caller file http://www.phpkitchen.com/seagull/tmp/roleMgr.phps 2. the main class http://www.phpkitchen.com/seagull/tmp/RoleMgr.phps 3. the super class http://www.phpkitchen.com/seagull/tmp/Manager.phps the incorrect error i get is Fatal error: Class rolemgr: Cannot inherit from undefined class manager in /var/www/html/awarez/www/roleMgr.php on line 4 enabling/disabling APC and restarting Apache several times in a row does not reproduce the error consistently. With APC enabled, sometimes the error appears, other times not. Is there a flush cache option or some kind of workaround you could recommend? if providing the actual files would help please let me know, cheers demian turner
