I've experienced a bug which if will get confirmed can make esp8266 (or nodemcu) useless in a "real environment". After few years of "being connected but not touched", device which has a simple http server stoped responding.Restart doesn't help. I connected it to serial port and realized that "init.lua is missing". I cannot reupload it. After performing file.format() it started working correctly.

Any ideas what can be reason of the problem?
Thanks!

You write "years"... I guess you have had an ESP8266 based board for at least a few years in use?
What is your firmware version, can you share your http server code? Are you sure your power supply is still working fine after all the "years" you have had the module running?

Yes, power supply is still working, peak 2 peak voltage is bellow 80 mV. Node mcu is 0.9.5 version and http server is based on this solution with memory optimization through flash. I thing that the problem can be caused by flashmod. Is it possible?
