(was: 1.19.0)
> The release check bug in tiered memory manager of hybrid shuffle
> ----------------------------------------------------------------
>
> Key: FLINK-34544
> URL: https://issues.apache.org/jira/browse/FLINK-34544
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Network
> Affects Versions: 1.20.0
> Reporter: Yuxin Tan
> Assignee: Yuxin Tan
> Priority: Major
>
> The `TieredStorageMemoryManagerImpl` has a `numRequestedBuffers` check when
> releasing resources. However, this check is performed in the task thread,
> while the buffer recycle may occur in the Netty thread. As a result, it may
> incorrectly throw an exception when the release is too quick for the vertex,
> which has almost no data.
> We should fix it.
