Lightroom using too much RAM

Same problem here.

Something news ?

Does anyone have a solution for this? I am having the same problem. I watch RAM consumption climb to 95% of my 48 gigs just sitting there in library mode. 

What you see is correct behavior.

There are several factors in play. First is the amount of data the running apps on the system have loaded. Second, when that number exceeds the physical memory in the system, the excess is put on disk and the OS pages app data in and out of physical memory as needed. Third is the amount of app data in active use. If that number exceeds the physical memory by too much, paging disk activity will slow the system. (This is why editing 50MP images in 8GB memory is a bad idea.) Fourth, an OS does it's best to minimize paging by using all of the physical memory and by having the most active data in that memory. That's why 98% of memory was used. 

The memory use in Task Manager for an app is the amount of that app's data that's in physical memory. When you closed Lightroom, the app data dropped 33GB and the physical memory in use dropped 13GB.

Just a thought for those who use Windows. ( I don't know how Mac uses it.)

Have you disabled Virtual memory in the Windows setting? You will always need virtual memory to be enabled. It is best to let Windows manage it.

This could be a problem if there is not enough memory, it goes to Windows and offloads it to the virtual memory. Even though you may have ample RAM, Lightroom still seems to use it. 

Having the same issues since today. Before it worked just fine. It always crashed the whole computer. Macbook M1 16gb Ram. Normal export settings. Never had problems before even on smaller machines.

Same problem. If I leave LR running, my iMac will eventually crash (screen goes blank, have to reboot). If I'm at my computer, I get a dialog telling me I'm out of memory, showing LR Classic using 63.x GB (which is weird because I only have 32 GB). I updated to LR Classic 13.2 today, we'll see if the problem persists. (One wonders if anyone at Adobe is monitoring this thread...)

LR Classic 13.1

iMac Pro

Intel Xeon

Radeon Pro Vega 56

Sonoma 14.2.1

Same Problem here. 

My work around for now is: edit 2 Fotos -> restart Lightroom -> edit 2 Fotos -> restart Lightroom .... you get the picture. 

LR Classic 13.1
Windows 11 Pro
Ryzen 5900X
RTX 3070 Ti
32GB RAM

All of the above: are these dual GPU systems - either a dual graphics laptop, or a desktop where one screen is connected to a motherboard connector?

Integrated GPUs use shared system memory. GPU memory usage tends to increase over time, and a GPU can use a very large amount.

The standard advice is to disable any integrated GPU, to avoid conflicts.

I keep having the same problem for a long time as well.

Is it normal that after a short period of time the app uses 15,7GB of RAM (of 16GB) and the app keeps freezing (including mouse movement)? When I turn off the app, Windows 11 with other apps take 3,5GB but when I run Lightroom it goes up to 12GB very quickly. When I start masking it goes up to 15GB and the app starts stuttering and occasionally freezing. I almost can't use the new lens blur function because it keeps freezing for a minute or so after activating it.

I was thinking of increasing RAM size to 32GB but, as I can see in the previous comments, even 64GB doesn't help.

It is annoying. There must be some kind of a problem. I usually have to turn off every other app to be able to use it 😞

Hi, 

I have the same issue with LRC is using over 35Gb of RAM and exports are failing due ti insufficent memory. I am trying to export a single photo as a Jpeg after I have edited it. 

LR Classic 13.1
Windows 11 Pro
i7-12700F
AMD 6800 XT
32GB RAM

After a lot of searching and testing I can't help but think that this is a bug within LRC.
