azagrebin opened a new pull request #10682: [FLINK-15247][Runtime] Wait for all slots to be free before task executor services shutdown upon stopping URL: https://github.com/apache/flink/pull/10682 ## What is the purpose of the change #10161 introduced canceling and waiting of all tasks in TM to release resources and exit before shutting down TM services on stop. #10034 assigned a separate memory manager per slot and #10330 introduced dynamic slots and state to `TaskSlotTable`.
