Lightroom uses all memory during sync

Just wanted to add that I have given up. Spent the last full week trying every option to sync, to no avail.

Going to try some Lightroom alternatives (Luminar, RawTherapee) as Lightroom classic is now completely unusable... it uses all system memory and crashes my iMac with 32gb of ram... Every. Time. I. Open. Lightroom.

I survive with a non nuclear option, without deleting my 20k+ library from cloud (Weeks of sync with my poor internet). I use MemoryClean during the sync process, multiple times. With some tries, I complete the sync. Hope it can help a little before Adobe find the solution.

Same problems see my post  Lightroom CC impossible to use in Mojave

I just talked to a support guy. According to what he said, Adobe recognizes this as a known problem: RAM is not freed when syncing and it may reduce performance or even collapse Lr and your PC/Mac. They seem to be working on it and an update should appear some time soon. No dates, but at least a recognition of the issue gives us some hope... ;-)

In the meantime, I can use Lr because I executed the "nuclear" option: I deleted all synced data (Preferences / Sync). Now I keep syncing to the bare minimum I need (until the problem is solved). If I add hundreds of new photos to sync performance can get really bad, but in those cases I simply restart Lr.

Hope it helps.

Entering a old issue as a new member.

So so very long, read thru all of it, did not notice one possible discussion.

CAMERA RAW CACHE.

I noticed several System Information listings, one talked about memory cache size (that is not CAMERA RAW CACHE), noted at least one member had something like 40GB for CAMERA RAW CACHE, but was syncing thousands and thousands of images.

So, assuming you have the room, bump CAMERA RAW CACH up, like 100 GB. The amount depends on the total sum of the images sizes, not how big one image is, not how big your sensor is, but the sum of all you are working on.

Increasing CAMERA RAW CACH will improve performance in Develop, and any other CPU or MEMORY intensive function,

Where is an official response to this matter? It seems to be a few of us. I have been using LR since 2007 but over the past month I have not been able to use it at all.

LR ends up using 60GB RAM (I have 32GB), it slowly builds up and of course the computer becomes unresponsive.

I just installed an additional 16GB, I originally had 16GB hoping to solve the issue. It used to eat up about 30GB and now that I doubled it, it uses double and I get the same results. Plainly frustrating and I have downloaded Capture One as I am seriously thinking of moving away from Adobe after being more or less a lifetime user of their products.

Iha e tried everything under the sun: uninstalled, optimized catalogue, etc. I have searched for answers online and I am going to go on Twitter now as Adobe will either fix it or I will other places and forget they even exist.

Its shameful what they have done and should issue a public apology, refund money, etc. but FIRST they need to solve this yesterday!

Hi,

I've exactly the same issue here : all memory is taken and no syncing possible at all !

last news

I'm recovering the original pics from LR CC, and I created new Catalogue in LR CC Classic, I disabled the GPU aceleration in LR CC and LR CC Classic, Now I can import the pictures in my new Catalogue, I can reveal the raw photos, the memory is normal and the CPU same situation. The search of location and detection of face was activated and now are working fine

Pending: recovery all pictures from LR CC and remove them all from LR CC, the last, when LR CC catalogue will empty, I will activate the sync with LR CC classic.

I'm Using the last version 8

I decided to delete all of the synced data and start over.  So far that seems to work.

Lucky for me I only use the mobile apps for my own personal use to edit and rate pictures.  I do not share them with anyone there.  So starting over was better than spending any more of the many many hours I have already spent trying to resolve this issue.

Thanks.

I have the same issue. After having to revert to a backup catalog since my main catalog suddenly was missing half of my library, it had me reset the sync data and now it never completes and uses up all of my system memory. In fact, Classic is virtually useless unless I launch and immediately pause the sync. It has been happening before the latest update. I have a large library of 84000 photos and videos.

While Adobe is wasting time implementing crappy, half-working nonsense things like face detection, major issues like this still persist that make it virtually unusable for me. This may finally force me off Lightroom if they can't fix it soon. My contract is up in January and will have to make a decision if I want to waste another year on dealing with this problem.
