Issue Number : 339291a
| Issue | When an error occurs during the process of dropping a TS or DF and a rollback is performed, a new DF is created with a DFID that should have been reused. The same issue can also occur during TS state changes. |
| Cause | The section performing rollback during TS state changes and DF drop processing is not protected by a lock, causing problems during concurrent processing. |
| Solutions | Modified to release the lock only after the rollback processing is fully completed, thereby protecting the corresponding DFID. |
