Yingjie Cao commented on FLINK-26568:
-------------------------------------
Update: After two days of repeating running, I reproduced the issue. From the
heap dumped, I can see that downstream task has requested partition, but no
data received (credit available). At the server side, there is no subpartition
view/reader. I guess maybe something wrong happens, the resource at server side
has been cleaned up and the client did not get notified. Another suspicion is
that the server failed to initialize the handler pipeline and the client did
not get notified.
I will try to enable the debug log and reproduce the issue again to see if we
can have any findings.
