I believe there’s a bug in the replicas in TU8: they’re not responding to REPLCONF GETACK *, which I’m using to check connectivity when I get a WAIT command.
Note that I also pass the next stage NA2 (WAIT relies on acks). But this logic is at odds with TU8 (WAIT does not rely on acks).
I do have a horrid hack to conditionally have WAIT return max connected clients when I get 0 acks… this will make me pass TU8, but I rather not do that.
