Use "netstat -nar" to see which routes have been cached. You should be able to delete the metrics associated with a cloned route by doing "route delete ipaddress". > net.inet.tcp.keepidle: 14400 > net.inet.tcp.keepintvl: 150 > net.inet.tcp.always_keepalive: 1 These would have nothing to do with what you're seeing.
