hub shutting down subscriber source

[cppfuns]

hub shutting down subscriber source, it is over desired chan size and grace period over (hub/hub.go:174){"current_length": 100, "target_max_channel_size": 100, "chan_capacity": 400}

Excuse me, is this error normal? How to fix

[sduchesneau]

It's usually when a subscriber (incoming connection) does not read data fast enough, so instead of accumulating tons and tons of data in a buffer and going to OOMkill, it closes the subscriber that is not reading fast enough.
There is no general fix, it warns that it is closing a connection. Maybe that connection was already gone but not closed, etc.
Is it causing issues ?

It seems that no special data problem has been found at present, but this log will occasionally appear on the terminal
