says you ran out of RAM. Given that this happens after a fairly long while, it sounds like you have a memory leak somewhere.

Dear ESP_SPRITE,
how can I identify a memory leak

You could use heap tracing for that. But before resorting to that, I suggest taking a long, hard look at your code to see if you're not allocating something and then not freeing it; that's basically what a memory leak boils down to.

Dear ESP_SPRITE,
Thanks for the help... there was a code like this
esp_err_t err_is_charger_locked = load_int_value("isLocked:", &isChargerLocked);
if (err_is_charger_locked != ESP_OK)
{
ESP_LOGE(TAG, "Error (%s) loading to NVS", esp_err_to_name(err_is_charger_locked));
}

where as the isChargerLocked is not initialized that caused the memory leak. after initializing now its working fine..thanks again for the support.
