we’re facing an issue related to RAM corruption, and I’d appreciate your input on how to handle it.
Here’s a summary of the situation:

1. The entire application runs on a single core of the ESP32.
2. We initialize EEPROM with 4000 bytes using EEPROM.begin(4000)
3. At startup, we read a configuration structure (225 bytes) from EEPROM and store it in a global variable in RAM.
4. This structure is read only once after reboot — we do not access EEPROM again afterward.
5. The structure is then used in various parameter calculations.
6. Initially, everything works correctly — calculations are accurate for the first 5–6 hours.
7. Suddenly, calculations become incorrect, indicating that the structure variable has been corrupted in RAM.
8. We do not modify or update this structure during runtime.
9. Interestingly, after around 10 minutes, the calculations return to normal — suggesting that the structure variable somehow "corrects itself."
10. This hardware has been running fine for 10 days, and this issue has occurred only once.

How can we detect and handle such a case where a global RAM variable gets corrupted and then seemingly recovers, even though we don’t explicitly touch it?
