Stephan Ewen closed FLINK-6231.
-------------------------------
Resolution: Abandoned
This issue has been inactive for very long and changes to the code have been
big since the issue was reported. I close it because it is no longer applicable.
> completed PendingCheckpoint not release state caused oom

> Key: FLINK-6231
> URL: https://issues.apache.org/jira/browse/FLINK-6231
> Project: Flink
> Issue Type: Bug
> Components: Runtime / State Backends
> Affects Versions: 1.1.4
> Environment: linux x64
> Reporter: Chao Zhao
> Priority: Major
>
> My cluster got one jobmanager and one taskmanager. jobmanager oom repeately ,
> with jobmanager.heap.mb setting to 256 and 1024.
> oom triggered at same scene: check point completed quickly, while these
> completed check points still in task queue in CheckpointCoordinator.timer
> without taskstate being disposed.
> one of my checkpoint with taskstate is about 10m, so about 90 completed
> checkpoint caused oom with heap size 1024m. hprof file proved this, can
> provide if needed.
> I have checked PendingCheckpoint.finalizeCheckpoint, not sure if it should be
> dispose(null, true) instead of dispose(null, false).
> I have no idea about how to make my taskstate much less
