Service exceeds -R limit but
if service listens on ports below 1024 I can see '...(looping)...' in syslog.
if service listens on ports above 1024 there isn't any entry in syslog.

This is a feature, but I do not understand its rationale:

                                if (sep->se_family == AF_INET &&
                                    ntohs(sep->se_ctrladdr_in.sin_port) >=
                                    IPPORT_RESERVED) {
                                        /*
                                         * Cannot close it -- there are
                                         * thieves on the system.
                                         * Simply ignore the connection.
                                         */

This change was made by Theo de Raadt in 1997, maybe he can explain the
rationale?

I do not understand why the errors are suppressed for non-reserved
ports, and also only for AF_INET but not AF_INET6 or AF_UNIX.
