Hi Forideal,
Do you mean you have 700 slots per TM or in total? How many TMs do you
have? And how many slots do you have per TM?
Also, when is the screenshot taken? It is after the job is fully initiated?
It seems you only need 1k+ network buffers.
Thank you~

Hi Forideal,
which Flink version are you using? If you using 1.9 or older, have a look
at the memory setup [1] and config docs [2]. If you are using 1.10, it
should be enough to increase* taskmanager.network.memory.**fraction* and
*taskmanager.network.memory.**max*. You shouldn't use *taskmanager.
