ESP32 memory leaks WIFI and MQTT

@Robin,

After flashing new firmware to the ESP32, disabling Bluetooth, saving my wifi settings using the following:

var ssid = 'xxxx'; 
var pswd = 'xxxx'; 
var wifi = require('Wifi');
wifi.stopAP();

wifi.connect(ssid, {password: pswd},function(){
//    console.log('Connected to Wifi.  IP address is:', wifi.getIP().ip);
    wifi.save(); // Next reboot will auto-connect
});

I get the following memory (after sending a ESP32.reboot):

>process.memory();
={ free: 4021, usage: 79, total: 4100, history: 0,
  gc: 0, gctime: 3.2 }

I found that my board does run the event wifi.on('disconnected',function()), at least sometimes. So I am trying the following code:

var wifi = require('Wifi');
var iwico = setInterval(wico,999999999);
wifi.stopAP();

wifi.on('disconnected',function(){
  //print("wifi disconnected");
  console.log('Wifi disconnected');
  clearInterval(iwico);
  iwico = setInterval(wico,1000*30);
  
});

wifi.on('connected',function(){
  //print("wifi connected");
  console.log('Connected to Wifi.  IP address is:', wifi.getIP().ip);
  clearInterval(iwico);
});


function wico() {
  console.log('trying to reconnect');
  wifi.restore();
}

function fmem() {
  free_mem = process.memory().free;
  print('free mem: ' + free_mem);
  setTimeout(fmem,1000);
}
fmem();

After performing a ESP32.reboot, I get the following:

>process.memory();
={ free: 3985, usage: 115, total: 4100, history: 0,
  gc: 0, gctime: 3.382 }
free mem: 3981

And as long as my Wifi doesn't disconnect it seems to stay steady at 3981. Shortly after I shut off my WIFI, I get a few error messages and then my memory drops to 3963. It continues to drop each time it tries to reconnect. After a couple of minutes, I turned my WIFI back on. Just before I turned it on the free memory was down to 3895. After it finished reconnecting it dropped more, down to:
3859.

Then it stays steady ad 3859. If I wait a few more minutes and turn off my WIFI again it doesn't seem to catch the change in WIFI status. If I manually type in wifi.getStatus(), I get the following

={
  station: "connected",
  ssid: "",
  bssid: "00:00:00:00:00:00",
  channel: 0, rssi: 0,
  htMode: "HT20",
  authMode: "wpa2",
  mode: "STA",
  powersave: "modem"
 }

For some reason my ssid is now deleted. Any idea why it does that? Maybe I'm shutting my WIFI off too quickly. If I turn my WIFI back on, it doesn't re-connect a second time. I'll set it to run overnight and see how much, if any memory loss I get if I don't manually shut off the WIFI.
