Two troubles with new 1v97 v on EspruinoWiFi

FIFO_FULL message comes on load.
1v96 worked fine. At least I've never recieved this mistake. But I could not be 100% sure with 1.96 as I'm in the procees of building my system and always update the code adding new fitures

I provide modified sample of the code which caused the problem. The solution to connect WiFi was to comment the code with flow-sensor and also do not put ANY pin in to the input mode. Flow-sensor is library written by Amperka and it woked absolutely fine with 1.96 and 1.95. I have not modified any part of this library

var HOSTS = ["192.168.1.92", "192.168.1.93", "192.168.1.95"];
var WIFI = [
  ["Alhimik" , { password : "" } ],  //0
  ["Alhimik_N", { password : "" }],  //1
  ["A-Alhimik ", { password : "" }]  //2
];
var INIT_OPTIONS = {"HOSTS": [0], 'WIFI': 0, 'ISSTART': 0, "Name": 'EspWater'};
var wifi = require("EspruinoWiFi");

var L = {
  'LED1': require("ledHandling")(LED1),
  'LED2': require("ledHandling")(LED2),
  'A5': require("ledHandling")(A5, 1),
  'A6': require("ledHandling")(A6, 1),
  'A7': require("ledHandling")(A7),
  'B1': require("ledHandling")(B1)
};

E.on('init', function() {
  USB.setConsole();
  console.log('started');
  L.LED1.On();
  //INIT_OPTIONS.ISSTART = 1;
  setTimeout(wifiOn, 1000);
});

var wifiOn = function(){
  console.log('starting WiFi');
  console.log(WIFI[INIT_OPTIONS.WIFI][0] + ' - ' + WIFI[INIT_OPTIONS.WIFI][1]);
  wifi.connect(WIFI[INIT_OPTIONS.WIFI][0], WIFI[INIT_OPTIONS.WIFI][1], function(err) {
    if (err) {
      console.log("Connection error: "+err);
      L.LED1.blink(50);
      setTimeout(wifiOn, 60000);
      return;
    }
    console.log("WiFi connected!");
    L.LED1.On(0); L.LED2.blink(100);
    for (var i in INIT_OPTIONS.HOSTS) {
      setTimeout(ccon, 5000 * i, INIT_OPTIONS.HOSTS[i]);
    }
  });
  return;
};
