I’m seeing the exact same thing. The application crashes and has to be restarted. Debugging it I see: Received a SIGPIPE: Broken pipe in EthernetClient::write. I also use HomeSeer and the issue is much worse when the OpenSprinkler plugin is enabled although I also can get the same thing by just using the web interface for OpenSprinkler. Seems like the code may not be handling cases where the other side drops the connection for whatever reason or possibly it has difficulty handling multiple simultaneous requests???
