> The flink 1.16 offers hybrid shuffle to combine the superiority of blocking
> shuffle and pipeline shuffle. But when I want to test this new feature I face
> a problem that it may cause deadlock when it running.
> Actually, it will run well at beginning. However, when it runs to a certain
> number it may failure for the buffer size and if I set a bigger size it may
> running without data execution like the picture. So I want to ask the cause
> of this problem and a solution.
