P: Desktop Memory leak on M1 Machines

[Minh0D4D]

Hi!

I am a software developer. Recently, my Lightroom CC (version 4.2 - 20210301-0713) is very slow . A close look at activity monitor reveals that the app consumes too many threads and memory (attached photos) which freezes the app.

@Rikk Can you help me forward this to the development team?

Thank you so much!

Just adding my experience with the same issue. I've been running into this problem for a couple of months now. Memory is completely consumed by Lightroom while performing some actions.

Using:

MacBook Pro 13" M1

16 GB Ram

500 SSD

thanks for reporting. I hope Adobe would resolve this issue soon. It has been 3 months since I reported the problem.

Just upgraded to today's update of Lightroom Classic and already it seems to be much less memory hungry...

Lightroom 5.0 on 14" MacBook Pro Max 

I have a new MacBook Pro 14" Max with 64GB of memory. This replaced a 13" M1 2020 Macbook pro. I used Lightroom with cloud sync on both machines. I've updated the 5.0 on both. Both are also running Monterrey. 

On my new M1 Max MBP, I am experiencing what seems to be a memory leak that results in my system running out of application memory. This manifested when exporting a number (100+) of CR3 RAW files into TIFF and also just browsing through purging/editing 900 freshly imported RAW files. Lightroom gets up to 40+ GB of memory being consumed.

I've attempted to reproduce this on my older 13" MBP M1 but I cannot reproduce the issue on that laptop. 

Is anyone else experiencing this?

Runaway memory usage is a sign sometimes of a bad install:

First Reset Preferences then Clean Reinstall

This procedure works for both Lightroom Classic and Lightroom Desktop.

If you are using Lightroom Desktop it can change the location of your local storage. 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.

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

Thanks for the quick reply. I did these steps and then imported a new batch of RAW files but I'm still experiencing the issue. 

[Rikk Flohr: Photography]

I've asked some engineers to review the thread. Stand by please.

I'm experiencing the same issue on a 16 inch M1 Max 64GB when just doing edits and masking. The ram is at 30-40GB consumed in about 25-30 minutes. Have seen this happen on multiple occasions.

[stephend94954148]

I have an M1 mac book pro 13 inch with 16gb of memory. I am having the same issue. Just doing some minor editing memory used by LR classic will go as high as 16gb memory used. I have done the reset and reinstall and it is still doing the same thing. Just now memory use hit 13gb. not good.

There's quite a few people on this thread saying "Me too" but only a single vote at the top, so if you're affected, please go hit that button as it affects the priority given to fixing it.

Just wanted to say I'm having the same issue.
I'm using release 11.0 and camera raw 14.0 running in macOS Monterey 12.0.1 on a M1 machine.

This has been an issue since at least the previous version of LR Classic. However, I was able to run fine after turning off GPU acceleration. But now I'm facing the same issue even thought I have it turned off. 

Photoshop has a memory bandwith where you can fine tuned it for you system, I think LR should have the same thing. 

Keep the good work, thanks

"I'm using release 11.0 and camera raw 14.0 running in macOS Monterey 12.0.1 on a M1 machine."  This thread is about Lightroom Desktop 5.0 - not Lightroom Classic. You may want to look in the Classic forum to see if there is a similar thread there. 

[beckswalters87]

Also having this problem, got the new 16inch pro max with 64gb memory! I have only installed Lightroom classic from creative cloud onto the computer (no other software yet), working on one set of photos (around a thousand) and in two hours it told me to force quit because of memory using around 30/40gb three times.  Would love a solution, thanks 

[jonayoni]

I'am on a Macbook Pro M1 16go and i have exactly the same Issue (Lightroom Cloud or Classic).
Lightroom use a maximum of RAM with Swapping too! ( i tried, uninstalled et reinstalled the soft... it's the same thing)
I can resolve the issue by disabling GPU accelaration but lightroom become very slow...
We need a software update 😞

[douglasw4731150]

Can confirm the same issue on our M1 Max 64GB 16" machine. LR has a memory leak.

[fastson99]

Editing one RAW 25MB image with "Lightroom 5.0 arm64 [ 20211012-0002-a1240ed ] (Oct 12 2021)" then closing Lightroom (Memory pressure graph).

Disabling GPU acceleration for image processing makes the software behave more normally.

[mikebrodt]

I cna concur that there seems to be some kind of memory issue. I was using Lightroom CC for about an hour and noticed the fan on my M1 Max 14" MacBook Pro starting to spin (a extremely rare occurance I've noticed). I checked that activity monitor and Lightroom was using 32GB of memory. I was able to quit and relaunch and it was back down 6.49 GB, but quickly climbed to 8.15 without me doing anything at all in the application. I'll keep an eye on it.

Hey there, 
I am very upset with my new iMac 2021 16/256 machine. I just use adobe photoshop and lightroom classic which taking too much ram and using swap memory. I talked with adobe support team they weren't able to fix my issue. 
Any idea? what i can do in this case? 
Thanks 

[dj_paige]

How much memory is "too much"? How much do you want it to take up?

I have seen occasional reports of memory leaks; but other than that, Lightroom Classic uses as much memory as it needs.

What version NUMBER of Lightroom Classic? We need the version NUMBER and not words like "latest" or "up-do-date".

And did you see my screenshot i have added? This is not normal that using. IS THAT NORMAL TO YOU?

[dj_paige]

No I cannot see the attached file, as my web browser will not show attached files here. Better you should include your screen capture by using the "Insert Photos" icon.

[Jao vdL]

The memory pressure you are seeing is a bit much for just Lightroom and Photoshop open indeed. There is a known (but very strange) memory leak bug in Mac OS X running on M1 machines when you have modified the color of your mouse pointer in the accessibility panel. This is very strange but solves a lot of these issues for people. So if your mouse pointer looks any different than black with a white outline, try resetting its colors in the accessibility system preferences.

Otherwise, the last Monterey update fixed a number of memory leak issues (not the mouse pointer one apparently) so if you haven't fully updated your OS do that now.

There are lots of reports of bad memory leak issues on the M1 machines. Apple needs to still fix a lot of their code clearly.

My mouse is black with white outline
