Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/36113 As part of debugging https://github.com/pytorch/pytorch/issues/35863, I discovered that the unit test would timeout during clean shutdown. Looking into this further, it looks like there is a race in `_on_leader_follower_report_shutdown_intent` when multiple followers call the same method on the leader. To fix this, I've ensured we have an appropriate lock in `_on_leader_follower_report_shutdown_intent` to guard against this. I ran the test 500 times to validate that this fix works. Closes #35863 ghstack-source-id: 101641463 Test Plan: 1) waitforbuildbot 2) Ran the test 500 times. Differential Revision: D20884373 fbshipit-source-id: 9d580e9892adffc0c9a4c2e832881fb291a1ff16 |
