   @SbloodyS 
   I'm sorry if my previous description was unclear. This issue is mainly about 
fault tolerance in sub-workflow. 
   
   Below is a detailed reproduce.
   
   there is the schedule tree:
   ```
   MAIN_WORKFLOW
       SUB_WORKFLOW
           STEP1->STEP2->STEP3->STEP4->STEP5
   ```
   
![1](https://github.com/user-attachments/assets/ca086bcc-9835-42d5-8c4f-3581fa14360b)
   
![2](https://github.com/user-attachments/assets/26d99e55-d693-4c35-9e63-eae60758de5a)
   
   
   1. execute MAIN_WORKFLOW
   2. stop and start master-server 3 times :
   
   
![3](https://github.com/user-attachments/assets/664f0f70-8fdd-4aca-ae07-98f34e95551a)
   
   then the SUB_WORKFLOW executed 3 times, and are all running and be 
controlled in master:
   
   
![4](https://github.com/user-attachments/assets/0a05b900-94d8-4b34-baeb-8aec46c86f92)
   
   finally, they are all finished:
   
   
![5](https://github.com/user-attachments/assets/88c5e44d-53e5-4539-b08e-7a8228d74fc2)
   
   
   i tried to created a branch to fix it :
   
https://github.com/reele/dolphinscheduler/compare/dev-usable-fix-all...reele:dolphinscheduler:fix-takeover-wf?expand=1
   
   and that works well.
