Strange behavior with SPIFFS about esp8266-react

[rjwats]

I would be wary about saving to the same sectors of flash memory that frequently in your code. All NAND flash has a limited durability and will fail permanently after enough writes:

Out of interest, what is it you are trying to write so frequently?

I have a status file that i need to persiste the atual state of my brew, in case of eletrical fail

Some people have experienced similar issues with ESP32:

espressif/arduino-esp32#1781
nodemcu/nodemcu-firmware#915

There might be some suggestions in those threads which could be of use.

FWIW, I second the "avoid frequent writes" mantra. Unless I'm mistaken, the library used in this project to interface with spiffs is the Arduino ESP8266 Core library. This library appears to offer write-caching which could solve both the timing and wear-leveling issues discussed. Good luck, I'd be interested to hear how things end up!

The problem is the simuntaneous save in SPIFFS. I changed the loop logic and worked! Thank you.

Glad you figured it out!
