P: (Win) Consumes RAM during import and fails to release afterwards

deleted

Another day, another frustrating import; Soon I need to update my plan, with this problem, I wonder why I would pay...

WHAT IS THIS!

Camera Raw virtual memory: 14317MB / 15908MB (89%)
Camera Raw real memory: -150405MB / 31817MB (-472%)

Cache1:
NT- RAM:0,0MB, VRAM:0,0MB, Combined:0,0MB

Cache2:
m:1071,7MB, n:0,0MB

U-main: 115,0MB

Do you know if anyone is looking into this?

Have a look at this:

Lightroom open:

Camera Raw virtual memory: 707MB / 15908MB (4%)
Camera Raw real memory: 645MB / 31817MB (2%)

Lightroom after Import:

Camera Raw virtual memory: 10914MB / 15908MB (68%)
Camera Raw real memory: -77440MB / 31817MB (-243%)

Real memory is negative?

Will we here anything somehow? 10 days... No info requested or update from a dev

Thank You!

Here is some system info when opening LR after testing and imported 355 images.

I've opened a bug for the team to review. They may contact you directly for more information. 

Thanks for your report and the refinements. 

can anyone else test this?

Its really awefull to work like that and close and restart LR after each import

LIGHTROOM CLASSIC BLOQUEA EL PC, CONSUMIENDO EL 99% DE LA MEMORIA RAM.

Buenas tardes,

Contesto en este mismo hilo para comentar un problema similar con la memoria RAM y la solución alcanzada, por si puede servir de ayuda a alguien.

(Si he de abrir un hilo nuevo, por favor decídmelo.)

Sin realizar ninguna edición, solamente haciendo tareas de ordenación,  etiquetado de fotos y sincronizar con la NUBE, provocaba que LrC consumiese el 99% de la memoria RAM, siendo imposible (en 5 minutos) realizar tarea alguna en LrC y dejando el ordenador bloqueado.

He estado buscando por toda la WEB y he ido anotando las indicaciones que se comentaban en distintos sitios acerca del consumo excesivo de RAM.

Realizando dichos pasos, tengo mi sistema como sigue:

- Lightroom Classic actualizado a su versión 13.5. El catálogo está en un SSD (1TB) dedicado con 840GB de espacio libre.

- La caché de Camera RAW, está en otro disco dedicado, con un tamaño máximo de 150GB.

- La memoria RAM de mi sistema es de 64GB.

- Tengo habilitada la aceleración de GPU, en modo AUTO.

- Sistema operativo Windows 11 Pro 23H2, instalado el 2024/06/01 y totalmente actualizado, en dos SSD de 2TB cada uno (montados en espejo) y disponen de 700GB de espacio libre.

- Procesador AMD Ryzen 9 3900X 12-Core Processor 3.80 GHz

- He actualizado los controladores de mi tarjeta gráfica NVIDIA Geforce GTX 1660 SUPER, instalado NVIDIA STUDIO version 560.81 de fecha 2024/06/08.

- He borrado las preferencias.

- He probado instalando nuevamente cada una de las versiones de LrC, desde la 13.1.

Por último, - He localizado las últimas ediciones realizadas, que por su mayor tamaño, pudieran generar problemas en el catálogo.. Las he sacado del catálogo, y esto ha resuelto el problema.

Espero que a alguien le sirva de ayuda.

Saludos desde Barcelona.

This is an incrdible joke. I also saw memory shoot up. I open LR, its stable at 3.6GB and stays there. I import 200 images, 5GB sRAW total, and RAM shoots up to 17GB usage, thats 13GB, why? its more then twice the full raw image... dont tell me previews are bigger then the raws lol. I then restart LR after that and RAM is fine again and can edit the images and ram will sit around 6GB

(UPDATE: Please also read my comment below as a reply. I have identified when this extensive memory consumption occurs).

The problem has started to occur, or at least be noticeable, in the last few days. When working in the Development module on an image, Lightroom's use of motherboard memory surges to over 15 GB. I have 32 GB on my Windows 10 stationary PC. But this grab of over 15 GB causes the PC to not respond anymore. I have to wait until I get control of my mouse again and then shut down Lightroom and restart it.

This must be a bug. Today, just now, this happened when working on an image from a Nikon D810 with a dng file size of around 45 megabytes. I ran the Lightroom denoise, and was editing a few masks (subject and background selections with a few adds and subtracts using a brush mask) when the PC stopped responding. Looking in Task Manager, I saw that Lightroom's memory usage was over 15 GB. After restart of Lightroom and continuing to edit, I see that Lightroom memory consumption is currently only 3 GB.

Background information: My Lightroom Classic is updated to the newest version now, but this problem also occurred before I performed the last Lightroom Classic update. I installed a new graphic card a few days ago, going from a GTX 1660 Super to an RTX 3060. Graphic card driver is fully updated with the Studio driver version from Nvidia. This freezing of the PC caused by high Lightroom memory consumption seems to have started after putting in the new graphic card, but I do not see why that should be. Lightroom performance tab is telling me my system is capable of full GPU utilization (it was listed as limited only with the GTX 1660). I have the setting here on "auto".

This must be a bug. It is happening consistently and often, and I have to shut down Lightroom very often to clear out the memory usage. Today's episode shows clearly something is wrong, because it happened while working on the very first photo, it happened quite suddenly (while working with a few masks), and the memory usage is now down again after a Lightroom restart.

App version: Lightroom Classic version 13.0.2, Camera Raw version 16.0

OS version: Windows 10, fully updated, stationary PC with 32 GB RAM and a 12GB graphic card (RTX 3060)

To reproduce: I just work in the Develop module for a while. I am not sure if this is happening only or because of working with masks.

Expected result and actual result: Using over 8 or 9 GB RAM becomes too much for my PC and certainly for many others. Using 15 GB or more RAM creates a show-stopper situation. There should be no need to take a hold of so much RAM. Expected result therefore is better memory management in Lightroom Classic.
