Fatal error: Uncaught Error: Access to undeclared static property: Phalcon\Di::$_default

my environment:
windows7 + xampp-win32-7.1.7-0-VC14-installer.exe + phalcon_x86_vc14_php7.1.0_3.2.1

my codes:

try {
	$di = new Phalcon\DI\FactoryDefault();
	
	$loader = new Loader();
	include BASE_PATH . "/app/config/services.php";
	$config = $di->getConfig();
	
	$loader->register();
	
	$application = new Application($di);
	$controler = $application->handle();
	echo $controler->getContent();
} catch (Exception $e) {
..
}

error info:

Fatal error: Uncaught Error: Access to undeclared static property: Phalcon\Di::$_default in C:\xampp\htdocs\brh\public\index.php:18 
Stack trace: 
#0 [internal function]: Phalcon\Di->__construct()

there are no errors on normal operation,the error occurs when I request twice continuely in javascript:

var $content = $('<div></div>');
$content.load(url1, params1, function (response, status, xhr) { //error will not occur on this request
	$content.load(url2, params2);  //error will occur on this request everytime.
});

I also found that when my computer disk is busy, the error ofen occur.
