LRC is slow and crashing randomly, also crash during export.

[David Daffie]

Hello,

Since Adobe chat can't help me (the engineer just closed the chat because he simply didn't know anymore what to do?) I'm asking here for help.

I've used Lightroom for a while, but had issues with slow responsivness, sometimes crashing etc..

So I installed 2 weeks ago Lightroom Classic, but it has more or less the same issues.

It is slow, not so responsive and sometimes my screen flickers, go dark, photo's freeze during post processing in pixels, .. and exporting is after 10 sec freezing and LRC is crashing.

I have a performant system:

- AMD 5800X3D

- 32 GB ram 3200Mhz

- Nvidia 3090 24GB

- W11 2H22 all updates done

- drivers of all components are up to date

Someone that had semiliar issues and can point me in a direction?  Not the standard things like, updates, reinstall GPU drivers, ... 

I used LRc on way less performant systems, and it worked like a charm.  I don't know what is going on.

[David Daffie]

Ok last thing now I've checked:

I import my photo's in LRC directly from my SD card onto my PHOTO folder on my NAS.

I post process the photo's and export them into a subfolder JPEGS in the same location on the NAS.

I've now copied a specific folder with my RAW files to my C: drive, updated the folder in LRC, and started exporting to the subfolder JPEGS in the same location on the C: drive.

All pictures exported well without freezing or whatsoever.

I find this strange, because I have a 1GB connection full duplex to my NAS and copying around 80MB/s.  Ideal world this would be 100MB/s, but.. When I check the connection from my PC to my NAS via PING, I have an avarage roundtrip of 0ms (so basically <1ms).

I think the bottleneck here is the NAS but WHY?

I don't want to change my workflow.  That is why I have a NAS.  I don't want to copy to my C: and then have to copy all over to the NAS.

Anybody else using the same method as me, directly going to the nas for import without an issue?

[David Daffie]

And another update:

I was too soon with celebrating.  Also now, during post processing, LRC crashed.  A lot of errors and screen flicker, dark, ...

So the move of the folder to a C: drive was not the fix.

Your C: has less than 20% free space and it should help if you move some files from that disk.

[David Daffie]

Ok did some cleaning: 

Free: 416GB out of 953GB

I'll let you know if this helped 🙂

[David Daffie]

I thought it felt a little snappier when, all of a sudden, LRC stopped responding. Also, my Brave browser is freezing at the same time, as I noticed (also before). However, I already rebooted the PC, started LRC without any other applications running, and the behavior remains the same.

So no luck in SSD free space.

[johnrellis]

As Jao mentioned, flickering of the screen and crashes during Develop and Export are typical symptoms of problems with graphics drivers. On the other hand, your experiment of processing files on the local disk rather than NAS doesn't fully align with problems with the graphics processor, though it's remotely conceivable that differences in timing of access to the photos is proving GPU issues.

So I think the next step is to authoritatively determine whether the issues are caused by the GPU:

1. "DirectX: NVIDIA GeForce RTX 3090 (31.0.15.4617)"

That's the latest Nvidia Game Ready driver (546.17). But Adobe and Nvidia recommend Studio drivers for Adobe's apps, supposedly being more stable than Game Ready drivers for creative apps, where the focus is getting high-performance game patches out quickly and less on stability and correctness. Try installing  Studio driver 546.01:

https://www.nvidia.com/download/driverResults.aspx/216398/en-us/ 

2. Are you overclocking or otherwise modifying the default settings of the graphics processor, e.g. with MSI Afterburner or Nvidia's utility?  Using the graphics processor with anything but the default settings is known to trip up LR. 

3. Start Windows in Safe Mode with Networking, which is the only way in LR 13.0 and LR 13.0.1 to completely disable LR's use of the graphics processor. Do the bad symptoms go away after using LR for the requisite amount of time?

4. If the problems don't occur in Safe Mode With Networking, then set Preferences > Performance > Use Graphics Processor to Off. Do problems (except for Export) go away?  

[David Daffie]

Ok thanks for the info.

I'm installing the studio drivers now.  It make sense it would be the GPU considering the screen flicker etc.. but in all other applications, Photoshop included, I cannot replicate these issues.

I also tested my GPU in 3DMark and Cinebench without any errors.

I have not OC or modified my GPU, except updating to the latest FW in order to enable Resizable BAR.

I'll post the results.

[David Daffie]

Ok back with more news:

I installed the drivers and at first, again: felt more snappy, and I post processed a lot of pics without any issue.

But with the export... it freezes.

Also my browser, freeze..

And funny enough, when I check my export folder, there are not 60 pictures in, but only 8 jpegs and numbers are 6, 8, 21, 25, 26, 27, 31 and 45.

So it did export some pics, but a lot it skipped or..?

[Jao vdL]

So one problem might be solved although you want to test the safe mode thing also but this is a good sign that just processing works well with the driver change... The crashing on export observation combined with the browser freeze makes me think this might be a hickup with the networking stack. Classic might be crashing on the export because of this and the networking stack getting stuck will also get your browser stuck. So I would look into that. Might be a bad ethernet card or a bad ethernet cable or issues at your switch or NAS. 

[johnrellis]

"It make sense it would be the GPU considering the screen flicker etc.. but in all other applications, Photoshop included, I cannot replicate these issues."

LR uses the graphics processor much differently than other apps and has been tripping over driver bugs in parts of the drivers that apparently aren't well-tested by the manufacturers.

" with the export... it freezes."

Unfortunately, a LR 13 preferences bug prevents you from disabling the use of the GPU for export. So do the step 3 (Safe Mode With Network) test above to verify the export problems are indeed triggered by the use of the GPU.  Hopefully the preferences bug will be fixed in LR 13.1, due in a couple week.

"So it did export some pics, but a lot it skipped"

LR exports photos concurrently and out-of-order, taking advantage of the multiple CPUs. So if it crashes in the middle, you'll see just those photos that completed.

[David Daffie]

So, I restarted in safe mode with networking.

I got there the annoying message: ctfmon.exe: System detected an overrun of a stack-based buffer....

Searched what this error could mean and solutions.

Did SFC/DISM and other stuff, including a CLEAN BOOT.  Error was still there but.. I booted now into W11, normal but with clean boot.

Without any post processing, I did the export and all photo's were exported.

I'll try tomorrow to do some post processing and export afterwards.

[Jao vdL]

That sounds like good progress. From what I understand from googling that error and the DISM process this means you had corrupted system files due to file corruption or even malware installed. That would definitely explain the behavior so fingers crossed that this solves your issue.

[David Daffie]

100% sure no malware.  I did several tests.

The error is still there in Safe mode.  Strange but.. no issues when booting in normal mode.

But SFC and DISM and other commands didn't pop up any issues.

[johnrellis]

"The error is still there in Safe mode. "

Then it's almost certainly not an issue with the graphics driver. Windows disables the GPU in Safe Mode, so it's not possible for LR to access it.

If it's still the case no problem occurs when exporting photos from the local C drive but does when from the NAS, that's the next suspect. There have been very infrequent reports here about issues between LR and NAS.  Which brand/model?

[David Daffie]

The NAS: Synology DS415+

No issue with the NAS itself.  I copied (to free up disk space) around 150GB data from my C: to the NAS.  No issue and it also hit almost the max speed of 108MB/s.

I had another crash.. I had Teams open and tried also Edge as browser.  LRC freeze at a random point, explorer.exe crashed (I know because my taskbar was gone) and Edge and Teams were black screens.

I could start explorer.exe again via task manager.

I'm really getting desperate and thinking about a format C:

The only thing is that all other applications, including Photoshop, Filmora, Davinci etc.. just run fine.

[johnrellis]

LR uses the computer and accesses file systems with much different patterns than other apps, so it's often the case that LR is the proximate trigger of problems with other underlying causes.  For example, a few have reported problems with the TrueNAS devices on Mac, where it's just LR that triggers Mac OS itself to crash (clearly a NAS driver bug).  Your situation is smelling like that -- while it's possible it could be a LR bug, it looks much more likely the issue is elsewhere.

[David Daffie]

Hate to say it but during holidays I will be probably formatting my PC.

This is really bothering me..

[Andrew31408254qdz8]

I'm using Lightroom 13-3 and can confirm this is still a major issue that I'm running into over and over and over. My business is basically dark right now because I can't edit or export photos without Lightrrom freezing and crashing.

[Jao vdL]

Hate to say it but this really does sound like a hardware issue. I would first suspect the GPU. First thing to try is to turn off the GPU in Preferences->Performance. This unfortunately due to a bug in the latest Lightroom 13 does not turn off the GPU for exporting but at least you can see if it no longer crashes in post processing. It will be slow but if it still crashes your hardware issue is elsewhere and at least you have that eliminated. Lightroom really taxes all parts of people's systems and often hardware issues only show up in Lightroom simply because it taxes it in ways other software doesn't.

[johnrellis]

Unfortunately, LR 13 Export ignores setting Preferences > Performance > Use Graphics Processor to Off -- it uses the GPU regardless of the setting. The only way to test whether the graphics driver is causing the problem is by booting Windows into Safe Mode With Networking.  But simply seeing System Info will be an easy first step.

[Jao vdL]

That's why I suggested testing post processing and not exporting since the OP also experiences crashes and very strange behavior (flickering, dark screens, freezing) just in post. Just realized that another cause of this might be a failing system hard drive/SSD.
