Question

Consuming large amounts of memory

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.

I'm in the same boat and basically my work around is to monitor memory demand and when it climbs too high I switch off syncing and restart Lightroom Classic. I then tend to run it as much as possible with sync off. It's a pain!

It's the same issue for me and it is clearly LR sync related. I'm using LrC 14.0.1 on Mac Mini with M1 chip. When LR sync is turned on, MacOS Activity Monitor shows the application virtual memory keeps going up linearly all the way to something like 90 GB which kills it. I closed paused syncing, closed LrC and reopened it. Now the Acitivit Monitor shows that it's memory stays stable around 2GB, which is much more reasonable.

Please help investigate and fix this issue. Very frustrating.

Same problem here, LR Classic using up to 90+ Gb of memory space. Causing very slow proces and overloading my Mac mini M2. I have to stop LR edvery 30 minutes or so. I can'f run a business on this!!!

If you have cloud sync enabled, then it's very likely that the issue is related to files being stuck in the sync queue. See post above by @esrauscht that explains how to check and fix. Pausing sync will also stop the excess memory use, but does not resolve the stuck file syncing.

Hi, this is very helpful for me!, but one question, before I delete images in Sync Issues folder on Light room cloud do I need to Stop Synching all collections in Lightroom Classic on desk top to avoid images being deleted from Light room classic ?

After chatting with the Adobe Support, I found a solution that at least works for me.

I logged into https://lightroom.adobe.com/. In the left menu under "All photos" there was an album which is called 'Sync Errors' or similar (I currently don't have it anymore). Photos that did not sync correctly are shown there. I deleted all of them (from the cloud). That I tried before but it did not help.

The hint that helped me was also emptying everything in the "Deleted" folder.

After that I started to sync another album from LR Classic and the sync went through normally while the memory usage stayed normal. I can see all photos withing this album now online.

Maybe this can also help you. I hope the faulty behavior will not return.

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.

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.

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.

Try the steps suggested by @Rikk Flohr: Photography

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.).

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.

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

Close Lightroom
Restart the computer
Use the Adobe Creative Cloud App to uninstall Lightroom.
Restart the computer
Install Lightroom via the Creative Cloud App without launching any other programs.
Restart the computer
Launch Lightroom
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.
