Fatal Error:cannot Declare self-referencing constant ""
This is an error in the YII framework
Error file: framework\db\cdbcommand.php
Error content:

Public function Prepare ()
{
if ($this->_statement==null)
{
Try
{
$this->_statement= $this->getconnection ()->getpdoinstance ()->prepare ($this->gettext ());/******** This is the line error ******************/
$this->_paramlog=array ();
}
catch (Exception $e)
{
Yii::log (' Error in preparing SQL: '. $this->gettext (), Clogger::level_error, ' System.db.CDbCommand ');
                        $errorInfo = $e instanceof pdoexception? $e->errorinfo:null;
throw new CDBException (Yii::t (' Yii ', ' Cdbcommand failed to prepare the SQL statement: {error} ',
Array (' {error} ' = = $e->getmessage ())), (int) $e->getcode (), $errorInfo);
}
}
}

Situation Description: Generally do not appear this error, that is, do not know how to run a site for a period of time (about 3-4 days) after the report this error, only restart Apache will be restored, but after a period of time will still appear.

Ask for advice, thank you!

------Solution--------------------
Not the original error of Yii, I don't know.
But on the Internet only to find your this and yii related issues, no one else you have ....
You're going to have to keep track of the mistakes you've given, you might find problems.
Since the visit is frequent, it may be related to insufficient system resources.
