High memory usage

[defaultg2wls6l1ad25]

For months now, Lightroom CC has become the most bug filled useless piece of software I've ever had to use. 

It hogs memory like you wouldn't believe - has to be restarted regularly (every 2-3 pictures worth of editing) because it become unusably slow.

Exports fail regularly with 'Unknown error'

Denoise fails regularly with 'Unknown error'

Denoise crashes my Nvidia display drivers on occasion - that really messes up my machine.

I'm an IT expert so I know my machine is well spec'd and configured to run Windows 11 efficiently. I have no problems with any other software breaking things and I do a fair bit of image and video processing. 

Why is Adobe allowed to get away with charging subscriptions for this PATHETIC poorly written and obviously untested rubbish?! I am so frustrated and angry as it takes hours to do the most simple things now. It's absolutely APPALLING.

Please provide the information at Help->System Info, down to and including the GPU information (we don't need anything and don't want anything after that)

Details added to original post

[defaultg2wls6l1ad25]

Hi. I don't need a cabin heater thanks. Not sure why you're trying to advertise here. Bit pointless really. As for your advice on getting the system information - you're a bit late to the party.... Try looking at my original post. I've also got a case open with Adobe (see above) their only suggestion is to clean install all Adobe products. If their software is that bad and they have no solution other than that then they really are idiots! I want a technician to look at my installation of Adobe software and tell me what's wrong. 

[Ian Lyons]

Do you have cloud sync enabled? If yes, then it's likley the reason for your issues. Also, if yes, then try Pausing cloud sysnc to check whether doing so helps.

[defaultg2wls6l1ad25]

Hi,

No. I don't use the cloud for anything. No Adobe cloud. No Onedrive (not even installed on the machine). The app and the catalog live on SSD. 

I'm currently editing 1 (just one!!) picture and memory usage is 20.1GB of the 32GB available. Lightroom is massively unresponsive.

I've uninstalled and re-installed. I've cleared all preferences and manually re-added them. I even shelled out £500 on a new GPU which has speeded up denoise (on the odd occasion it actually works) but otherwise no different. It's a total joke, it really is.

I don't believe there is a solution to this - apart from Adobe fixing their horrendous software.

[dj_paige]

By @defaultg2wls6l1ad25

Still you should check to make sure that cloud sync has not been accidentally turned on, and that OneDrive has not been accidentally turned on, causing the problems you describe.

[defaultg2wls6l1ad25]

Thanks. for getting back to me. See above. Cloud is not in use. As I said before I don't have Onedrive installed on my machine so it's not likely to be turned on accidentally... Lol.

I don't see how sync would cause develop mode to use 19GB of memory when editing a picture in any case.....

[Ian Lyons]

I was referring to cloud sync within Lightroom Classic. I've attached a screenshot below of where it's enabled/disabled.

Mine is disabled...

[defaultg2wls6l1ad25]

Sorry for the late response. It's off. I have zero usage of the cloud storage.

[defaultg2wls6l1ad25]

So..... My last post was deleted for being truthful about how utterly attrocious Lightroom is.  I somehow get the feeling the focus of these forums is all wrong. You can't tell Adobe how bad they are because someone might not like it. I give up. I really do. 

Lightroom has been fantastic for years. They change the model, make it subscription and then pump out dross release after dross release, none of them addressing the bugs they introduced with the previous release. 

Delete this if you like 'moderators' - I don't care anymore.

"So..... My last post was deleted for being truthful"

Your post was deleted for language. 

Feel free to clean it up and repost it.  We appreciate honest (and accurate) feedback but expect you to follow forum guidelines and maintain civility.

Lightroom will take as much memory as it can when running. I saw this behavior and it was crashing my system regularly, but only when I fired off a bunch of memory hungry tasks. 

For me, it turned out that one of my RAM sticks wasn't fully seated and it was triggering a memory error - but not until higher memory addresses started getting used (in my case, >24Gb). As long as the actually memory access didn't go up that high, the system was stable. 

In my case, I was able to run a memory diagnostic and see a failure was up in memory, so I was sure it wasn't LR. I found the RAM stick not quite fully seated.

Thanks for your reply. I'm almost certain that won't be my issue, however I will run a memory diag to be sure. If there was a hardware issue like that I'm fairly sure I'd have seen system crashes, error messages in the system logs or with other high memory usage apps failing. My machine never crashes (even when LR causes the GPU drivers to fail), it just runs like a dog until I close LR.

Denoise crashes my Nvidia display drivers on occasion - that really messes up my machine.

DirectX: NVIDIA GeForce RTX 4070 (32.0.15.6081)

Something in the back of my head is telling me that something is not correct with the GPU. Now that is a very nice and capable GPU, and the driver is up to date. But why when it is apparently pushed a bit for the DeNoise AI, does it fail?. 

If you go and open up your computer to inspect that RAM , take a look at the GPU, is it falling out of the slot, is the auxiliary power cable loose (an assumption on what 4070 you have). And new? So probably no dust bunnies.

You may want to search in the community on 4070, and see other members posts.

Thanks. It's a brand new Gigabyte NVIDIA card. Fully working. No seating or power issues. If there were I'm sure I'd see machine crashes and errors in the system logs. My machine doesn't crash it just loses display for a few seconds until the default Windows drivers kick in and my 4k monitors are on something like 640x480 resolution!!! If I restart the drivers things come back to normal but a machine re-start is the only real way to be sure the system is clean.

[GoldingD]

Meant to include the following earlier, but I stumbled looking for the link(s). Other postings with 4070 issues.

The 4070 appears to be coming up in several postings, (unsolved) as a minimum, these:

• LR causing CPU Spiking/crashing - new build Intel 14900K
• Lightroom Classic takes 2:28 to start completely
• LR Classic doesn't open any exsisting catalog anymore
• Strong GPU and RAM usage in LrC
• Lightroom Class crashes on Collection Export as Catalog
• (Windows) Takes 1 Minute or more to move between images
• Moving between edit in photos is slow

Looks like a bug to me, either at Adobe, or at NVIDIA.

[defaultg2wls6l1ad25]

Thank you I'll have a browse through these issues....

[peterili]

Hello Andrew, have you found any solution to the problem? I have been having this same problem for months and it drives me crazy. I created new catalogue and everything went smoothly, no problems. Came back to the main catalogue an again the high RAM issue continued, checking task manager my RAM usage goes close to 30GB before the system freezes.

I read on some other forums that it could be something with the masking features, after substracting from some mask on an image in certain cases the memory usage starts to go up.

Whenever I start LR I can work for about 5 minutes and than the memory usage spikes.

Thinking about throwing the computer out of the window 😄

I spent dozens of hours trying to solve this issue - I am thinking about saying goodbay to Lightroom and moving to some other software.

Kindly let me know if you found any solution.

Many thanx, Peter

[defaultg2wls6l1ad25]

Hi Peter,

No solution as yet. I've upgraded to v14.0.1 and it's still as diabolical.

Currently speaking with Adobe Customer Support whose only suggestion so far is to fully remove all Adobe apps doing a full system clear up then re-installing. Utter joke!!

I've done that before, it didn't work - and it takes ages!

I'm pretty much done with Adobe now. Will have to bite the bullet soon and learn Affinity.
