WIZnet WIZ550io

I still cannot get DHCP to behave .. this code

E.enableWatchdog(10);

var eth = require("WIZnet").connect();
eth.setIP({ 
  ip : "192.168.254.248", 
  dns : "208.67.222.222",
  gateway: "192.168.254.100" });


var http = require("http");
http.get("http://www.espruino.com", function(res) {
 res.on('data', function(data) {
  console.log(data);
 });
});

Works up to a point. If I execute the get 6 times (one after another) .. manually .. so I wait for the get to complete .. they all work and pull the html back correctly.

The 7th time (always) I get "ERROR: No Free Sockets Found" and about 5 seconds later, the Espruino COM port disconnects from the PC. Have to reboot. I sometimes see a huge number of SPI TimeOut on TX messages before the COM port dies, but most often not.
