Tongotos freezes or hands and UI becomes unresponsive

Guardian

New to Tonfotos. Got my photos indexed after leaving it over night. Now that I have things ready. I was going to start with turning on “Store faces in images metadata”. It would start scanning photos but the whole application just locks up after that. UI is unresponsive, nothing works, cannot even minimize the app. Cannot show my desktop either with WIN+D key. It would leave a black window up. Is there any troubleshooting I can do? Or is it something I just need to leave running for a few hours again?

Running Windows 11.

Guardian First, how many CPU cores do you have? If less than 4 than that could be problematic, as program runs multiple processes in parallel.

Second, where your photos are stored? Is it local SDD/HDD? Is your C: drive on SDD? Main database is on C: and data transfer speed could be the issue.

Guardian

Andrey It’s a i5-12600, so I have 10 cores available.

Photos are stored on a NAS and I’m accessing it via local network. C drive is an SSD.

Andrey

Guardian Ok, thank you. Looks like it is not a hardware problem then.

Is there a reliable algorithm to reproduce the issue? Like do x, then y then wait N minutes and here you go… Or it is pretty random? How long it takes in general for program to get into that state?

That’s the tricky part. This starts happening right after I turn on “Store faces in images metadata” for the library.

It will scan a few photos and freeze.
I would force close it using Task Manager and boot up the application again.
It will scan a few photos and freeze. This typically happens within the minute I start the application.

I turned on the logging and noticed the log would stop the moment it freezes.

I once tried leaving it running for 2-3 hours and the log did not update in that time, nor did the app show any sign of unfreezing.

What I do know is that one of the processes when I look on Task Manager goes into “suspended” status. But the others are still running. But I don’t know how to check what the processes are doing and if other actions are happening.

It freezes here too, but the program is working in the background. I can see the CPU and processes are working… but the windows gets “white”. Win11 here too. This happens if its been running over the night here aswell. And I just right click on taskbar/icon and select close. Then open it again. v1.14.4 with CUDA.

Can you please turn it of to verify this is indeed what causing it?

Stig

Do you have antivirus running ? It never stops working here, it runs.. but the applications gui is unresponsiv.
Whats the last it writes to the log when it freezes… any errors before ? any long files it trying to read from a network drive and then “hangs”..
Any problems with other applications.. like is the graphic card updates (or correct drivers)
Device manager showing devices that are yet to be recognized and updated drivers ?

Guardian

Stig
I use Window’s native virus scanner.

There are no obvious errors in the logs. It looks like typical output and just stops. It’s not consistent where it stops too.

Drivers are up to date and windows update isn’t showing any updates I need to install. Other applications function just fine.

Stig

Putting Battery/mode into performance or turning off antivirus for a while?
Suspended feels like that the OS is giving the program less room (memory/cpu cycle).. how about turning off other programs in background.. I dont know, but using eliminating method to try to find whats causing it 😉

Guardian

Andrey
Yes. When I turn it off. The application does not freeze and this is how I’ve been running it so far.

Andrey

Guardian Ok, that narrows it down. Can you please send us logs that include freezing? More about logs here: https://community.tonfotos.com/d/26-making-debug-logs-in-tonfotos

I have submitted the log via email to support@

Andrey

Guardian Thank you very much for logs. Even if it looks like metadata update is the reason, logs suggest otherwise. There is something odd happening, it looks like backend is bombarded with folder rescan requests from UI, i have no idea why this is happening. Looks like metadata update is just the trigger for the collapse, but real reason is not there. What is most strange, this situatuion is unique to you, no one else had similar complains.

Can you please record and share a video of what is happening on the screen when this all is happening? Probabaly that will give me some clue why UI is bombarding backend with requests… You can use your phone to record what is happening, starting from the program launch.

Guardian

Andrey Sorry, I was out of town and didn’t get a chance to do this. I will record a video and send it to support@ shortly.

Andrey

Guardian Thank you for video! Am I right assuming that once you turn off storing facial information into XMP program works fine again?

Guardian

Andrey That is correct. When I turn off “store facial information” everything works normally without freezing. This is how I’ve used the app so far.

Andrey

Guardian Thank you, that is importnat piece of information, I hope it will help identifying the issue.

Andrey

Guardian Can you please check something for me? In the another thread we are discissing problem that looks similar but I am not sure if this is the same problem or not. In thier case hanging happens immediately after start and does not seem to be dependent of XMP feature. However it depends on Tonfotos version. It only is reproduced on 1.14.4 and above, but not on 1.14.3

https://community.tonfotos.com/d/953-tonfotos-hanging/14

Can you please check your issue on 1.14.3 version? Please don’t forget to turn off automatic updates in settings, or program will update itself again. Please don’t uninstall previous version, just install on top.

Guardian

Andrey Installing version 1.14.3 did not improve my situation. The moment I turn on “store facial information” it would start to check for changes and then freeze. Turning it off would stop this behavior.

However, I did proceed to install 1.13.7 and turned “store facial information” back on and found that it continues to “check of changes” in the library and doesn’t freeze. I left it running for about 1hr to finish this process. When it was done, I installed 1.14.6 and the application doesn’t freeze anymore even while “store facial information” is turned on.

So I suspected it was something in the checking for changes process in 14.3 and 13.6 that was causing the freezing.

I will continue to use Tonfotos with it this setting on for now and report back if it starts to freeze again.

Andrey

Guardian Thank you very much! That is very useful information!
