Loosing config file

[mwuerr]

I have now twice lost my config.ini.
I would say that seem to have a 1 out of 10-15 chance when I do a config change in a running system to loose the config.ini.
I have learned now and have downloaded a backup.
The system is still operational after the issue appears. I can use the webserver to upload a new config.ini.

Version: master - v9.2.0 - 2021-12-02

This is strange. Sometimes my config.ini is not saved, e.g. if the ESP32 is busy with image processing while configuration.
But I never loose the config.ini.'
Is it possible, that your ESP32 or sd card is slightly instable?

There is a request for implementing a full backup through the web interface. I have put this to the request list, but I'm not working on it currently.

[mwuerr]

Can you give me a hint how I can detect "instability". Is there anything in the logs that I should be looking for, or can you recommend me a stress test program?
I agree to your conclusion that it is most likely a hw related issue; otherwise others should see it also.
Of course I will monitor it; now logging is enabled; If it appears again I will post my findings from the log.

Can you confirm that:

1. xxxx-xx-xxTyy:yy:yy: task_autodoFlow - next round - Round File Server: Option to delete multiple/all files in a directory #4
   should count up to high numbers of round. Basically "Round #" shows how many time an image was processed since the last reboot.
   Correct?
2. ....= Main Started = ...
   is insterted into the log only after a reboot.

If those are yes's then the following log clearly shows that my device is regularily rebooting. Probably due to power issues.

I will follow the instructions from:
https://arduino-hannover.de/2018/07/25/die-tuecken-der-esp32-stromversorgung/
and
https://community.hiveeyes.org/t/power-supply-for-the-esp32/1859/4
and throw a few capacitors at the problem.

[friedpa]

1 and 2 is correct

[jomjol]

Additionally: capacitor helps and an access to the web server also can trigger a reboot. So a good hint on the overall hardware stability is an undistorted observation of the count e.g. over night. I can reach up to 200 round with a stable system before an unattended reboot.

I have a lot more rounds :o)

But I have seen over 1000 Rounds so far...
