Rui Fan updated FLINK-38804:
----------------------------
Description:
h3. The existing logic
When task encounters any exception, {{postFailureCleanUpRegistry.close();}} do
some cleanups.
[https://github.com/apache/flink/blob/7ba97419d200adef672b67c52c2b5a79f277cfda/flink-runtime/src/main/java/org/apache/flink/runtime/taskmanager/Task.java#L801]
TaskManager will shutdown if {{postFailureCleanUpRegistry.close();}} meets any
expetion, it works as expected to avoid poential bugs or resource leaks.
h3. Root cause and solution
The following unexpected exception occurred within
{{{}postFailureCleanUpRegistry.close();{}}}.
Cause: The shutdown sequence is incorrect. {{RemoteInputChannel}} depends on
{{ChannelStatePersister}} (which uses
{{{}ChannelStateWriteRequestExecutorImpl{}}}) to snapshot buffers. However,
{{ChannelStateWriteRequestExecutorImpl}} is being closed prematurely while
{{RemoteInputChannel}} is still active. If a new buffer arrives, the active
{{RemoteInputChannel}} attempts to use the already-closed executor, resulting
in the failure.
Solution: Ensure the RemoteInputChannel (or remote components) is closed before
ChannelStatePersister and ChannelStateWriteRequestExecutorImpl.

> h3. The existing logic
> When task encounters any exception, {{postFailureCleanUpRegistry.close();}}
> do some cleanups.
> [https://github.com/apache/flink/blob/7ba97419d200adef672b67c52c2b5a79f277cfda/flink-runtime/src/main/java/org/apache/flink/runtime/taskmanager/Task.java#L801]
> TaskManager will shutdown if {{postFailureCleanUpRegistry.close();}} meets
> any expetion, it works as expected to avoid poential bugs or resource leaks.
> h3. Root cause and solution
> The following unexpected exception occurred within
> {{{}postFailureCleanUpRegistry.close();{}}}.
> Cause: The shutdown sequence is incorrect. {{RemoteInputChannel}} depends on
> {{ChannelStatePersister}} (which uses
> {{{}ChannelStateWriteRequestExecutorImpl{}}}) to snapshot buffers. However,
> {{ChannelStateWriteRequestExecutorImpl}} is being closed prematurely while
> {{RemoteInputChannel}} is still active. If a new buffer arrives, the active
> {{RemoteInputChannel}} attempts to use the already-closed executor, resulting
> in the failure.
> Solution: Ensure the RemoteInputChannel (or remote components) is closed
> before ChannelStatePersister and ChannelStateWriteRequestExecutorImpl.
