セロリで次のコードを実行すると、タスクは成功しました:
ystd = date.yesterday()
task_obj = TelecomTask()
tsk1 = chain([task_obj.craw_allkeyword.s(1, ystd),
task_obj.save_allkeyword_date_pv.s(task_obj),
task_obj.save_allkeyword_date_pv_pct.s(task_obj)])
tsk_grp1 = chain(tsk1, group(task_obj.cal_allkeyword_week_pv.s(task_obj), task_obj.cal_allkeyword_month_pv.s(task_obj)))
task_group_array = []
task_group_array.append(tsk_grp1)
header = group(task_group_array)
callback = task_obj.set_telecom_allkeyword_data_date.si(task_obj,ystd)
chain(header,callback)()
そしてそのような結果：

しかし、チェーンをchordに変更すると、タスクは無限に再試行を続け、コールバックを実行しません。以下は私が変更したコードです：
chord(header,callback)()
そしてそのようなログ：

コードの何が問題なのですか？誰か助けて、ありがとう
