> Right now, if exclusive buffers for the input channel and one buffer for each
> subpartition would be allocated on start successfully but there would be not
> enough memory for the rest of the buffers(floating buffers, rest buffers for
> subpartitions), then we see nothing in the log about that(as I understand).
> So first of all, we need to check what logs we have right now about
> situations when flink doesn't have enough memory for all configured buffers.
> And if we have nothing (or not enough) we should add such a log.
