Sounds like a conflict with zend optimizer.
You can disable zend by commenting out this line in your php.ini file:
zend_extension ="path/to/extension_dir/zend_optimizer.so"Update:
php.ini settings look fine.
There is a bug report regarding file includes APC 3.1.8 that causes a fatal php error:
failed to open stream: No such file or directoryI would try removing APC and recompile version 3.1.7 and see if your errors go away.
