When you  receiving the following error in  system.log file: app\code\core\Mage\Core\Controller\Response\Http.php:44  [1] \www.pawan.com\lib\Zend\Controller\Response\Abstract.php:727  [2]  \www.pawan.com\app\code\core\Mage\Core\Controller\Response\Http.php:75  [3]  \www.pawan.com\app\code\core\Mage\Core\Controller\Varien\Front.php:188  [4]  \www.pawan.com\app\code\core\Mage\Core\Model\App.php:304  [5]  \www.pawan.com\app\Mage.php:596  [6]  \www.pawan.com\index.php:81 if you have no idea what file is causing this.
