Magento v1.4.1.1 multiCall错误

Question

我遇到了Magento multiCall的问题。我有一个自定义PHP脚本，用于更新商店中的产品。该剧本几年前成功运作，但随后突然停止了。

错误

    Fatal error: Uncaught SoapFault exception: [1] Internal Error. Please see log for details. in /htdocs/scripts/euronics_update.php:422
Stack trace:
#0 /htdocs/scripts/euronics_update.php(422): SoapClient->__call('multiCall', Array)
#1 /htdocs/scripts/euronics_update.php(422): SoapClient->multiCall('7a7bb80602974f5...', NULL)
#2 {main}
  thrown in /htdocs/scripts/euronics_update.php on line 422

我的代码

// collect 10 products information and execute as multiCall to speed up process
        //
        //$count_calls_array++;
        $count_running_pos++;

        //if ($count_calls_array > 10 || ($count_running_pos + 1) == count($data_all))
        if (count($calls) > 3 || ($count_running_pos + 1) >= count($data_all))
        {
            //
            // store product to Magento
            //

            if ($error_counter > 0)
            {
                echo "continued after error\n";
                $error_counter = 0;
            }

            try {
                $result = $client->multiCall($session, $calls);
            } catch (Exception $e) {
                $error_counter = 1;
                echo "* * * " . $e->getMessage() . " * * *\n";
                //echo "error occured, trying to restart. dump:\n".var_dump($calls)."\n";
                $result = $client->multiCall($session, $calls);
                echo "error resolved\n";
            }
            echo date('d.m.Y H:i:s').'---'.$count_running_pos.' -- '.count($calls).'<br>';
            ob_flush(); 
        flush();

            // clear array
            while (count($calls) > 0)
            {
                $tmp = array_pop($calls);
            }
            //$count_calls_array = 0;
        }

提前致谢！
