> 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.
