  can it be inadequate power-some power glitch/brownout? if you use esp8266 with it an connect it to same power source the total system power draw may change a lot e.g due to wifi traffic and may cause random power issues if it draws too much.

  I thought about it too but i use very good voltage regulators.

  @Gordon thank you for your suggestions and efforts! I tested a lot too. And I have come to the conclusion that sometimes reading and writing to storage is very slow. This is not a problem anyway, but if there is a delayed reboot after that, the memory will be cleared. But it also happens very rarely and I think it has to do with running out of memory.

  This strange code sometimes produced this error:

  function log(f){  
       if (require("Storage").read(f) == "undefined") {
        require("Storage").write(f,'1');
      }else{
        var n=parseInt(require("Storage").read(f))+1­;
        n=n.toString();
        require("Storage").write(f,n);
      }
  }
  
  for (var g=0; g<10; g++) {
  	clearInterval();
  	clearWatch();
  	console.log(require("Storage").getFree()­+'-'+parseInt(require("Storage").read('g­s4.pc'))+1);
  	log('gs4.pc');
  	setTimeout(E.reboot,2000);
  }
  

  Thank you very much!

  I use the MDBT42Q with the 2v09 firmware.
  I connected the ESP8266 to it.
  After 2 months of operation, the flash became empty!

  >require("Storage").list()
  =[  ]
  >require("Storage").getFree();
  =40960
  

  The code and the logs are disappeared.
  The device has been self-initialized, working, and can be connected.
  I tried another MDBT42Q yesterday and the same thing happened!
  Is it possible that the storage write could cause a problem?
  I do a simple log, I write very little data (basically i am writing a counter):

  function log(f){
       if (require("Storage").read(f) == "undefined") {
        require("Storage").write(f,'1');
      }else{
        var n=parseInt(require("Storage").read(f))+1­;
        n=n.toString();
        require("Storage").write(f,n);
      }
  }
  

  This log runs very rarely.

  I couldn't manually reproduce this thing maybe someone has a similar experience?
  This is very scary for me.

  I can connect to the device, but I don’t want to do anything else with it until there’s a suggestion.
  The power supply was continuous and i use a good quality adapter, voltage regulator and battery. I was able to connect to the device, I didn’t have to reboot, but the flash was completely empty. I used the flash to log in, but that couldn't be much data.

  I guess maybe there was some logging to Storage inside your setScan handler?

  I store the result of setScan in an array, but inside the http handler write the log. I log not only the errors but also the exceptions. I'm trying the fix, which is interesting! I attach the memory usage graph.

  This one may actually be unrelated - as @MaBe says the code itself should work fine. Are you writing to Storage from inside your application?

  Yes, i use it for logging

  It'd be good to try and track down why this is happening

  @Gordon You think well (as always)..the problem was basically caused by

  NRF.setScan(function(dev) {..}); 
  

  because it was still running when the require("http").get(...) started. It also produced several strange things after a few days... for example memory leak, http socket close error, even the temperature reading became inaccurate.

  Thanks for all the support!
