I am using xdebugger version "php_xdebug-2.0.2-5.2.5.dll" and also further versions.I mean latest versions like xdebug-2.0.4. But always i had a problem with these all versions. i.e, At the time of debugging suddenly stops debugging and got an error message "Port 9,000 is already occupied. Please configure the IDE to use another port". after this it doesn't work till to system restart. So please solve my problem or tell me is there any way to solve this.
