My Linux distributive is RedHat / CentOS 5.x i386/x86_64.

I am using custom put together Apache version 5.2.17 (both worker and prefork) modes with mod_php (PHP 5.2.17) custom put together too.

phpinfo() page shows "Thread Safaty" is 'enabled'.

My issue is latest ZendOptimizer version 3.3.9 does not provide thread safe extensions ( any longer. So it's needed to disable "Thread Safety" in PHP.

Could somebody assist me with setting up (*.ini options) or producing (configure options, make flags, etc.) mod_php with Thread Safety disabled

Please tell me is a few information needed.
