spontaneous disconnection from many peers #8931

I am noticing my node suddenly disconnecting from many peers at once where the disconnection is initiated by the other peer. I'm unsure at this stage whether the peers are simply disconnecting or banning, or what their versions are. I am currently debugging this and will update once I know.

Some debug:-

Looking like a non-issue, i.e. the disconnections are initiated from their end, probably all controlled by the same person.

Yes, please close the issue.
