Lightroom Classic CC 8.1 Build 1200465 uses all the available RAM

  • Updated 2 months ago

Hi there.

 

After the latest update of my Lightroom Classic CC I literally can ́t work with it anymore!

After a few minutes Lightroom occupies most of my computers RAM. I have a Windows 10 Pro with 16GB of RAM. Lightroom uses constantly over 12GB and slows down the whole computer.

 

It only uses between 15 and 25% of CPU in the same time.

 

My CPU is a Intel Xeon E5-1650v2

 

The Lightroom Catalog, Cache Files and Previews are all located on a (only for this purpose designated) SSD with 256GB. The original image files are on a local SATA drive with 3TB. GPU support is deactivated in the LR settings, because it is not a very fast GPU.

 

Why is Lightroom so slow and WHY is it using soooo much RAM??

 

By the way: Dear Adobe - I don ́t know if any of your employees reads this post... but I am VERY UPSET about the fact, that I pay 145 Euro a year for the photographers abonnement but I even are NOT allowed to contact a real support team with my issue! Thats ridiculous!

 

Thanks for any reply

 

Regards

Benjamin

Hi Benni, why did support say they couldn't help you? I tried looking up your account and there's no membership associated with the email address you've used to post here.

Yes, I have another email-address as Adobe-Account. Is it possible to send you the address via PN or sth like this?

Support did NOT say they couldn ́t help me, because I was not able / not allowed to contact them! Weh I try to navigate through the Adobe page to the support and there I naviagte to error correction, I only have the opportunity to post a message to the community forum. There is NO email support, NO chat support NO telephone support for me available!

My guess is you chose Lightroom (perpetual product) rather than Creative Cloud > Lightroom, from the list of products. If you choose Creative Cloud, then Lightroom it should give you right options (circled in red) once you drill down through the self help options:

Benni, 

I will leave Jeff Tranberry to work with you regarding the issues with contacting support. For your immediate Lightroom needs I will jump in.

The symptoms you describe look suspiciously like a bad install.  My recommendation is to do a clean reinstall following these steps.
  • Close Lightroom
  • Restart the computer
  • Use the Adobe Creative Cloud App to uninstall Lightroom Classic CC
  • Restart the computer
  • Install Lightroom Classic CC via the Creative Cloud App without launching any other programs.
  • Restart the computer
  • Launch Lightroom
  • Wait 5 minutes
If you still see the rampant ram usage and slower behavior after performing this install, then reset your preference file.  A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the 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.

Does the behavior continue after resetting the preferences?

I did everything exactly as you told me.
Sadly the RAM usage is not getting better. LR uses 14GB of RAM in IDLE. I do not make any task in LR, just LR is open, no other app, only my catalog loaded, but memory is at its max.

A long shot, but how many photos in the catalog Benni? And how many smart collections would you say?

In addition to Victoria's question, if you create a blank catalog and let Lightroom sit idle with the blank catalog do you see the memory creep?

Thanks for doing the install and preference set. It helps ensure we are chasing the right thing!

I have (beside the "standard smart collections") 9 SmartCollections and all in all roundabout 135.000 images in the catalog.

I know it is a big catalog, but far away from a huge catalog. And my hardware setup isn ́t that slow.....

Oh no, that's good, I was thinking of an issue investigated recently with lots of collections/smart collections, but that had more than 7 million photos!

With a empty, new catalog and 20 pictures imported, LR uses roundabout 2.5 GB of RAM.
The enormous high RAM usage can not be reproduced in this case.

What is the meaning of this? 
Is my LR catalog too big? I alway thought, that LR is a tool for professionals. I don ́t think, that my catalog is way out of the range of a average LR user...

Or is there any other problem with my catalog?

That helps. No, your catalog is not too big! It is only 1/3 the size of mine and mine is not that big. There are catalogs in the millions of images working happily around the world. 

Your catalog may have a problem however. Have you optimised your catalog recently? (In the File menu)

I optimised it on January, 3rd.


But I can try optimising again...

At first I thought optimising helped.

But it didn ́t.
Now it seems that the memory usage sometime falls down to a normal value (about 3-5 GB), but after a few seconds after such drop, it again raises to 13GB and slows down the whole computer.

(Everything in IDLE mode)

More good information thank you.  Let's create a copy of your catalog and see if it misbehaves as well
  1. On Computer, Open Catalog
  2. Select “All Photos Collection”(Library Module – Catalog Panel)
  3. Select All [Cmd]+[A]
  4. Right Click on first photo and select from context menu Stacking>Unstack
  5. Select All again [Cmd]+[A]
  6. File>Export as Catalog...
    1. Save as: TemporaryTestCatalog.LRCAT
    2. Where: Desktop so you can find it quickly
    3. UnCheck ☑︎ Export Negative Files.
Now, double click this catalog (it should still point to your original images).  Let it sit for 20 minutes or so and then close Lightroom. Wait a few minutes and then reopen Lightroom (still on the test catalog) and watch the memory usage.
