They are different things. Both the rate and the concurrency were exceeded
in the logs you posted.
* Concurrency = Number of simultaneous connections. (With slight "fuzz"
as a result of message latency between smtpd(8) and anvil(8) if
connections are sufficiently short-lived, lasting not much longer than
the time it takes smtpd(8) to deliver a connection status update to
anvil(8). Not a problem in practice.)
* Rate = connections per time quantum (still subject to message latency,
but much less important over the longer time scale).
