receive: Replica count exceeds replication factor although it does not?

level=debug ts=2021-05-27T00:57:03.170460586Z caller=handler.go:641 component=receive component=receive-handler msg="failed to handle request" err="replica count exceeds replication factor"
replicas: 6
receive.replication-factor=2

I don't really understand this, replica does not exceed replication 🤔

This might need more info, I suspect 2 replicas were just up. Worth to document this error/failure mode better

This is saying that a receiver A got a forwarded message from receiver B.

B said "this is copy number 6 of the time series."

A looks at it's configuration and says "huh, replication factor is only 2, so why did i get copy number 6? This must be a mistake"

I've been confused by this in the past too - partly because the error only showed up on the caller side.

Should be straightforward to make this clearer 💪
