Lightroom uses all memory during sync

Hi

When syncing Lightroom CC it ends up stalling with around 430 images to go and - after a period - my Mac warns me that I have insufficient memory, Lightroom stalls and I have to force shut down. Checking the activity monitor something strange is happening: Before reaching the last 430 images, the memory usage is around 4 GB, but then it slowly starts creeping upwards until it reaches the max 8 GB that I have. And it is all caused  by Lightroom (I run no other programs at the same time).

I have tried resetting preferences, deleting Sync.lrdata file and going back to an older catalogue. None of them resolved the issue.

Other users seem to have issue caused by them using Dropbox etc. I am using none of those.

I use a MacBook Pro 2.6 GHz, 8 GB RAM, OS X 10.11.6

Any ideas?

Thanks

Peter

I suppose this is the nuclear option. It’s good to know this worked for you but this is not a real solution. This problem is a total disaster for anyone who uses Lightroom Classic and weeks later there is no still no solution. Just got off my second tech support call I am no closer to a resolution. Guy just tried the same steps.

I use Classic but also migrated my catalog to LR CC.   I believe erasing all of my synced content would leave me with the inability to remigrate my catalog to CC. 

This all started when I had to restore a backup catalog and rebuild my sync data. The memory leak is so egregious, I cannot believe it would be difficult to find if it is given priority.

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!

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,

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.

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.

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 agree with you. LR unusable... just hope Adobe will solve this problem with update. After all these years an untrusted application. I moved all my catalogues & photos to a PowerBook Pro. See if it works better until a fix.

I think the reason you aren't getting any responses is because Adobe has started working with people individually to address the issues. I'd suggest creating a support ticket with Adobe and contacting them. You can do this through Support in your Adobe account profile.They've been fairly responsive and are currently working on the problem. Hopefully they'll be a public fix soon

Thanks for your help... see my post Nov 24th @ 11:14AM post only option is Forum no contact or support ticket available. Will just wait & hope they fix- already moved LR catalog & photos onto a Mac Book pro... reluctant to make it sync & loose all my live URL links. If & when they fix issue will export a catalog of all new imports & edits.

I think this may finally be fixed in v8.1 released today. I'm rebuilding my sync data again and it is still not complete but it seems like the massive memory leak is finally fixed.

When you refer to Syncing

Are you Syncing a folder to bring images into your classic catalog?

or are you syncing to send images to the cloud? to Lightroom CC (not classic)?

or syncing to the cloud for Mobile?

When the MAC claims not enough memory, I wonder if that is RAM, or is it hard drive space? The three possibility's may use different hard drive space, and it is probably no the Camera RAW CACHE, or the Temp, or the Scratch disk (OS)

Syncing from my public collections (making them public) to the cloud. Version 8.1 seemed to stop repeated slow syncing that I had to pause. Hope that helps.

Nothing is fixed here with the latest version...Left 30k images to sync overnight just to find Lightroom using 60GB of RAM, where I only have 16GB. Had to delete all synced data and start again by small batches.

ADOBE SUPPORT IS WASTE OF TIME.

Adobe, not only is the syncing a disaster, but it is a shameful example of ignoring users.

What reputable company would issue a product that fails to release memory until the product crashes?  The only solution I've found is to monitor Task Manager > Performance > Memory and keep an eye on that curve.  When it approaches 90%, I shut down Lightroom CC Classic and wait until the memory slowly subsides to normal, then reloading Classic - and then the process starts over again.  Today, I watched in exasperated expectation when it finally synched down 5...4...3...2...1 expecting it to hit zero, and then my computer would be free again.  No such luck.  The moment it hit 1, it started counting up again.

And what reputable company would allow this problem to fester for five months (the first complaint on this forum is in October 2018)?  Not releasing memory is coding 101.  At least your staff should acknowledge this problem, but no one from Adobe has even acknowledged it in this forum!  In fact the very first message in this forum is that this problem is not yet fixed.  Is the manager who released a product that fails to release memory still working for Adobe?  Why?

Not to mention that some basic information on synching is not even displayed.  For example, WHAT file is being synchronized now?  How much bandwidth will this process consume before it is finished?  Why can I not limit the daily bandwidth so I don't run out of internet bandwidth before the end of the month?  Why can't I see the number of files being uploaded, and downloaded?  When does Lightroom project it will complete the process, given the current bandwidth I'm using?  Why doesn't it tell me these things?

Adobe, you have left the marketplace open for a competitor to move in with a product that doesn't screw around with users' time and resources, and that works as expected.  I for one will be looking around.

This isn't inspiring. I had Lightroom on my Mac and was getting OS messages that it's not going to work with future OS updates, so I bit the bullet and bought the cloud version. It synced all the files in my catalog ONCE. Subsequent attempts to sync have resulted in this memory problem. At first, I could sync a handful before the memory problem and crash; now, it doesn't sync anything and the memory used is 90G, which is 16G of RAM plus a swap file on the startup drive.

I've had a few very long sessions with support people, but no solutions. This cloud solution is unworkable. I can use Lightroom Classic v 8.3.1 as long as I don't try to sync with cloud. A waste of $$, time, and trust.

Amazingly bad. Same thing happening to me. LR Classic uses all RAM and crashes machine. Every time it starts and resumes syncing several thousand photos.

Adobe has apparently done nothing for months to fix the obvious and fatal problem.
