Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute.

$driver_options = [
        PDO::MYSQL_ATTR_USE_BUFFERED_QUERY => true
];

$stmt = $xpdo->query('SELECT Clients FROM STATUSSERV');
if ($stmt) {
    $row = $stmt->fetch(PDO::FETCH_ASSOC);
    $stmt->closeCursor();
    print_r($row);
}
