Recently (possibly since 10.5.4) I am getting the following messages in the console every 15 minutes or so: 09/07/2008 20:43:02 mDNSResponder ERROR: mDNSPlatformWriteTCP - send Broken pipe 09/07/2008 20:43:02 mDNSResponder tcpConnectionCallback: error writing I know mDNS responder is a Bonjour process. I have "back to my Mac" turned off and have no services enabled in sharing. The Firewall in Leopard configured as "set access for specific services and applications". My machine is configured with the router IP address for DNS and the router itself gets the DNS servers from my ISP. Any ideas anyone?
