----------------------------------
Priority: Critical (was: Blocker)
> FineGrainedSlotManagerTest.testTaskManagerRegistrationDeductPendingTaskManager
> unstable when running it a single time
> ---------------------------------------------------------------------------------------------------------------------
>
> Key: FLINK-31297
> URL: https://issues.apache.org/jira/browse/FLINK-31297
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.17.0
> Reporter: Matthias Pohl
> Assignee: Weihua Hu
> Priority: Critical
> Labels: test-stability
>
> We noticed a weird test-instability in
> {{FineGrainedSlotManagerTest.testTaskManagerRegistrationDeductPendingTaskManager}}
> when switching to sequential test execution (see FLINK-31278). I couldn't
> reproduce it in 1.16, therefore, marking it as a blocker for now. But it
> feels to be more of a test code issue.
