Lightroom uses all memory during sync

[Loegtved]

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

Hi Peter,

We're sorry to hear about the memory usage, let us help make this right. Thank you for providing the information, could you please make sure that you're using the latest version of Lightroom CC which is version 1.2 by going to Help > System Info?

Regards,
Sahil

Hi. Is there any news here on this issue? I have been experiencing the same thing. I just came back from Peru and needed to import around 5k photos from various camera devices. I had no problem importing images with my GoPro, but from my iPhone, iPad, and Sony Xperia phone the software kept pausing saying I was running out of memory, even when no other programs were running.

Specs

Computer: MacBook Pro 15in 2016 with 16gb RAM

OS: macOS Sierra version 10.12.6

Software: Adobe Lightroom 6 (version 6.12, Camera raw 9.12)

My catalogue has 24,500 photos in it and was originally created back in 2016. I suspect that there is some bug/leak in lightroom which is causing it to overuse memory as I recently deleted every file on my computer except for my lightroom library. Would rebuilding the library help or creating a new one? I see that there are several articles online regardless lightroom leaks but would like an official answer as to how to fix it. Thanks.

I should note that when I say transferring photos with my GoPro, I mean that I imported the photos/videos directly from the SD card, not that that should make any difference...

[VUS Photography & Art]

Sahil, any news on this. I also ran into the same problem and from what I gather from all the above you, meaning Adobe, has gone silent ever since your initial reply not solving the problem. Can we get to a workable solution please? Your advise would be most appreciated...

Same thing happens to me. I'm syncing lots of pics from mobile (around 4500 raw images). I'm using Lightroom Classic CC Version 7.3. I've had to force quit LR 3 times now in the process of syncing, and I'm still not done. It's taking days. All 16 GB of memory eventually ends up allocated to LR and my OS (Mac OS 10.13.4) warns me that I'm out of memory.

[akbobrow]

Have you rebuilt your library? I was thinking of doing that when I get the time...

[highlandarr]

I am experiencing the same issue. Lightroom Classic takes up all free memory while (suddenly) attempting to sync thousands of photos. In fact, syncing has gone completely bonkers. The status in the corner says "syncing x,xxx" (some number in the thousands) photos. That number and the Sync Errors collection photo count jump around, up and down. It never needed to do this previously. I didn't just add thousands of photos to my library, they've been there all along. I only have a few hundred photos set to sync to lightroom mobile. When I look in the sync preferences, in the sync activities pane, there are 0 activities, 0 pending. Nothing reported at all. Meanwhile Lightroom is cranking away and sucking down all the memory, until it becomes unresponsive. It seems like this process will never complete. It also holds up the syncing of the photos that I actually want to be synced!

This is a major bug. Adobe, we need to hear from you about this problem. Sync operations should not be this opaque and disruptive. This is supposed to be a professional product, but I can't work like this.

Sounds like the same issue I just started having yesterday. I thought it might be from the 8.0 update released on 10/15 but from this thread it seems people have had the problem before the update. All my photos were sync'd as of 10/16 and when I imported some new photos to Classic on 10/17 it's as if the entire sync process started over again, only never finishes. Lightroom Classic either freezes up midway through syncing, gets stuck in a loop counting up then counting down or uses ALL APPLICATION MEMORY and I have to force quit.

The Creative Cloud desktop app meanwhile says "All files up to date" and the sync status in Lightroom Classic has ZERO ITEMS IN THE QUEUE. The only indication any sync is happening at tall is the small text above the nameplate in Lightroom Classic.

It seems to me like Adobe has changed something (behind the scenes) on their end requiring users to rebuild their sync database but that's just a hunch. Since most of my original files are stored on my desktop using Lightroom Classic (in sync'd collections) that is the machine that is most heavily impacted by syncing. All my other devices, laptop (using Lightroom CC) and iPad, iPhone are sync'd with no issues except their sync will not update with any new images imported with Classic- most likely because the sync on Classic never finishes.

[aristotelisd67259155]

Fully agree with all your statements below. Specially for the one that “Adobe has change something behind the scenes specially for the sync part. The reason that I agree so that all this issue has started suddenly without any change for my part except the upgrade of the macOS to the latest version, or at least it any an incompatibility between macOS and Lightroom was

I have the same problem. It’s unbelievable frustrating. I’ve bought a new computer, problem persists, gone to old LR backups, still there, opened LR and turned all preferences off, turned off GPU, deleted all Lightroom modules, reinstalled LR, started from fresh. Nothing works. Adobe support surfed in, had a look around, and left, problem unsolved. Looking at forums this is a widespread problem. Currently LR is unusable and I’m looking at alternatives, although with a heavy heart, with worries about a learning curve.

Just wanted to say: exact same issue here! For me it seems to have started after moving my catalog to a new computer. RAM usage is stable till about 4K photos left and then spikes to 20GB and hangs. SO frustrating to have this suddenly be broken when I depend on it for injesting photos.

[ryno2019asd]

I find an extremely painful workaround: I basically un-synced all my collections and removed a ton of photos, and then re-added them. It seems to have worked, although I still find Lightroom suddenly seems to be way slower than it was a few weeks ago.

[Yaakov Kossoy]

I tried that as well.  It did speed up until I started syncing again, then it slowed to a crawl.  Seems to be a memory issue with Adobe on the Macs.  And mine is a brand new computer.

[joshuamgbc]

Likewise, this issue seems to have appeared after moving to a new computer with my catalog.

[Yaakov Kossoy]

I'm running into the same issue as everyone else.  I try syncing my photos (around 6000) and it hogs all resources, including cache.  And I'm running on a brand new Macbook Pro (mid 2018) with 16GB RAM and 512 GB SSD.  I have images to edit and cull and I can't do that in LR if it keeps hanging.

[Anastasiy Safari]

Count me in!

All of a sudden Lightroom Classic CC 7.5 started to eat all memory (I have 32GB) and Sync count jumps up and down. I tried to restart, reset Sync, Delete All Sync Data, move Lightroom DB to other places - nothing helps! It starts doing that again over and over. It's Mac.

I checked file activity - it never accesses original photos during that, only database and temporary files.

Also Lightroom becomes very slow after 10-15 minutes of usage - all the same that you're experiencing.

[oakland_Mike]

I'm encountering this problem, too. It's occurring in relation to sync. I'm syncing a lot of images. The "All Synced Photographs" and "All Sync Errors" counts bounce around (mostly just adding more errors and reducing the "All Synced" count). Then, after a time, I get the Apple warning message about having run out of application memory.

[harlanh20529054]

This has become a disaster.  It is constantly trying to sync and every time I start Lightroom it resets some - with 2000+ sync errors that it tries to reconcile.  After about 500 the memory usage grows to over 20GB which for me is now going to swap files and renders the computer unusable.  By stopping and restarting the computer I eventually can get it down to zero but then the next time it starts over again.

To add insult to injury, changes I've made (primarily star ratings and pick flags but some edits too) on the online and mobile apps are not being synced ever.

This has become a useless function.  It started for me about a week ago and happened before version 8 and after upgrading. 

I have also deleted the Sync.lrdata cache file to reset things and while at first it seems fixed, within hours we are right back to the same problem.

THIS NEEDS TO BE FIXED!

[timothym44529554]

I spent some time on the phone with tech support yesterday and afterward I thought the sync issue may have been fixed because everything returned to normal but it turned out the sync just stopped all together which is why it seemed normal (when sync is running, lightroom is unusable).

Tech support had me try "Rebuilding Sync Data" in Lightroom preferences. The option is somewhat hidden. You have to go to Lightroom preferences>Lightroom Sync tab and hold down Option (Mac), (Alt on Windows) and a new option shows up where the "sync activity" box is. "Rebuild Sync Data" and "Generate Diagnostic Log" appear. Clicking "Rebuild Sync Data" makes Lightroom re-index all the collections that are "Sync'd with Lightroom CC" and re-start the sync process.

After attempting this a few times Lightroom seemed to be working normally and allowed me to work while the sync was happening but then slowly went back to having the same problem. I tried rebuilding it again and it seems to have stopped the sync entirely.

[Guest]

What phone number did you use to contact tech support... I have problem & can noyt find a phone number on Adobe site.

[GoldingD]

You can contact them using the web, to find the contact link yuou could click on Help in LR, clcik on Lightroom Classic CC Help...

and navigate thru the pages.

or, just ignore those steps, here is where that will send you:

Contact Customer Care

scroll way way down and find a link Contact US.

OK that gets you to:

Contact Customer Care

Click on Adobe Photoshop Lightroom. Scroll way down and click on Chat. start that Chat, ask for help.

[Guest]

Customer care does not have a phone number just a Forum Option.

[Just Shoot Me]

Choose something else than Troubleshoot. Like Licensing problem.

But honestly this is not specifically a LR Problem. Apple, OS X Mojave has something to do with it. So try posting over on the Mac OS X Mojave forum too.
