help with enabling apc, apd and memcache - xampp for windows

[srinivas]

Hello

I had attempted to Enable APC, APD and MEMCACHE on XAMPP for Windows.

I had removed the semi-colon before

extension=php_apc.dll
extension=php_apd.dll
extension=php_memcache.dll

in xampp\apache\bin\php.ini

I am using Xampp for Windows v1.6.6a

when I checked in xampp\php\ext\ folder, I find all php_apc.dll, php_apd.dll and php_memcache.dll files accordingly.

problem: APACHE is becoming UNSTABLE after ENABLING any of them (apc/apd/ memcache).

even XAMPP localhost (http://localhost/xampp) or phpmyadmin (http://localhost/phpmyadmin ) or whatever it is, donot run correctly, and when we check phpinfo, we do find APC and APD but not MEMCACHE. overall, apache is giving error when I enable the extensions continuously with occasional error message.

we were trying to restart XAMPP after that.

--------
please shed some focus on this, to help us use apc, apd and memcache in our php applications

thank you
