[PEAR] DB_DataObject calling stored procedures

[Derek Downey <derekd@xxxxxxxxxxxx>]

I'm having trouble calling stored procedures from DB_DataObject. The  
issue is, it seems to be losing database information when making  
multiple calls to the stored procedure (using mysqli). I want to make  
sure I'm making the call properly. I realize it's suggested to use  
MDB2 over DB_DO, but it's not possible in my situation to make the  
switch for the time being.

Below is my example code and the error I'm getting. It makes the first  
call fine, but it seems that adding more than one call increases the  
chance to cause an error, but not all the time. What I mean by this  
is, if i add a second call, it will fail occasionally (by hitting  
refresh). If I add a third call, the second call almost always errors  
out, causing any other calls to also error out. I just have no idea  
why it's losing database connection.

// Example Stored Procedure: //
delimiter //
CREATE PROCEDURE testSP( IN testParam TINYINT(1) )
BEGIN	
	SELECT CONCAT('TEST', testParam);
END;
//

// DB_DO Class //
<?php
require_once('DB/DataObject.php');

class TestDO extends DB_DataObject {}
?>

// TEST CODE //
<?php
require_once("TestDBDO.php");

// SET PEAR CONFIG OPTIONS //
if (class_exists('PEAR')) {
	$config = parse_ini_file('../data/pearConfig.ini',TRUE);
	foreach($config as $class=>$values) {
	    $options = &PEAR::getStaticProperty($class,'options');
	    $options = $values;
	}
}

DB_DataObject::debugLevel(5);
$obj1 = new TestDO();
$obj2 = new TestDO();
$obj3 = new TestDO();

$obj1->query("CALL TestSP(1)");
$obj2->query("CALL TestSP(2)");
$obj3->query("CALL TestSP(3)");

DB_DataObject::debugLevel(0);
?>

// DB_DO CONFIG FILE //
