   I found the trigger condition!The subtask has two Pre task, one for forbidden task and one for failed task. when we restart the failed task, the subtask do not run after the failed task complete, and the workflow stuck.
   We can resolve the problem by remove the forbidden task from the subtask's Pre tasks.

   > Hi @wanghaizhou , could you describe the steps to create the workflow's task? I can't reproduce this problem.
