Consuming large amounts of memory

[ichibod_com]

With the latest update, running on a M3 Max Macbook with 64gb ram running Sonoma 14.6.1, I open Lightroom classic and immediately ram starts being consumed until my computer runs out of disk space due to memory swap. I left it open for an hour and 20 minutes and was at 127gb of ram consumed. I don't even have to do anything before it runs away with the ram consumption.

Please fix this so I don't have to quit every 30 minutes.

There are sporadic reports of high memory consumption, but nothing has been identified as the root cause or is repeatable. 

Typically, this type of problem is due to a bad install. 

Recommended: 

Clean Lightroom Install Procedure

1. Close Lightroom
2. Restart the computer
3. Use the Adobe Creative Cloud App to uninstall Lightroom.
4. Restart the computer
5. Install Lightroom via the Creative Cloud App without launching any other programs.
6. Restart the computer
7. Launch Lightroom
8. Wait 5 minutes
   
   Preference File reset (because it survives an uninstall/reinstall. 
   This procedure works for both Lightroom Classic and Lightroom Desktop.

If you are using Lightroom Desktop, your local storage location can be changed. Please review this setting after resetting preferences. 

Reset Procedure:

1. Close Lightroom.

2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.

3. Overwrite the Preferences when prompted by the dialog.

4. Close Lightroom.

5. Restart Lightroom.

Try both of these steps in the order provided and report back if you are still seeing the same idle memory consumption.

Did it help? If not not, is Lightroom Classic configured to sync files with the Adobe Cloud? If yes, then check whether temporarily pausing cloud sync helps.

Hey @Ian Lyons,

I have reset preferences, uninstalled / reinstalled, and cleared caches.

If I disable sync, and then restart Lightroom Classic, I see very minimal memory usage when not doing anything in the app.

However, the moment I enable syncing, the memory usage starts creeping up, until the app eventually crashes. Meanwhile, the count of things syncing goes down a little and then appears to totally stop moving. I would imagine that you have a memory leak when retrying / erroring out or you're leaving files open or such things.

Disabling sync, once enabled, does not stop memory usage from increasing. To recover, you have to disable sync, and restart LrC.

This is a huge blocker to my workflow at the moment (I use LrCC to import on the go, and then I have LrC at home where I keep my archive, go through large albums, etc.).

@Freddie__ 

Are you using an Apple Silicon or Intel based Mac?

Actually, better that you provide your System Info as found in LrC Help menu. You can use the Copy button within the System Info dialog to capture the info, then paste into your next post.

Hey @Ian Lyons, 
I've just booted up an ancient (2015) MacBook Pro to test to see if this is an Intel vs Apple Silicon issue. I had to create a new catalog on my M2 machine as I've plugged the drives into the Intel for testing.

@Ian Lyons this doesn't seem to be just an Apple Silicon issue, memory usage on my Intel machine is now at 18GB (8GB physical installed) and there is no sync progress since an hour ago when I left it running.

[Ian Lyons]

Apparently, the issue has been observed quite some users with Intel machines, but much less so on Apple Silicon. I'll pass the info to QE.

[Freddie__]

Thanks @Ian Lyons, happy to be of any help I can to get this resolved. It's a huge pain to not be able to use the software right now.

[Freddie__]

I've downgraded to LrC 13.3 and this now has reasonable memory usage and sync is working again. I will attempt 13.3.1 once the sync is complete.

[esrauscht]

I am using Lightroom Classic 13.5.1 on a Macbook Pro 14 M2 Pro. My system shows exactly the same problems. As soon as sync is enabled the memory consumption is rising without any limit. The sync however gets stuck. When I pause the sync and restart Lightroom, memory usage is normal. Please fix this. I really rely on the sync function. 

[matthewn36417493]

I have the same problem on a MC Mini M2 Lightroom goes up to abut 42gb and then I get the application memory is full warning and I cant do anything else. This is really disrupting my work flow. I've tried all sorts to fix it including reinstalling from creative cloud and updating my OS. If anyone comes up with a difinitive answer I would really like to hear it.

[chip_nc]

I was having the problem of memory growing (once I saw it at over 200GB) and it had something to do with a problem syncing. Even though I had turned syncing off on all collections there were 92 images that it was trying to sync. After I paused syncing the memory stopped growing and the max I saw when working in LR was about 12GB and when doing nothing it was below 5GB.

[mdboulogne]

I experience exactly the same problem on my Macbook Pro M1 Ultra. Sync is so slow that it's practically unusable in any professional workflow (if it works at all) and Memory usage has often jumped to more than 200Gb after which it crashes due to lack of system memory. I really hope this problem will be fixe quickly with a next update.
