Question

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

    Hi, I have the same problem. I spent a long time in Adobe support chat trying to fix it, but got no diagnose and no solution. I use the last version of Lr Classic CC, purged caches, rebuilt previews, increased space for camera raw, etc. etc. I ahve tried everything, but Lr keeps eating up all available memory until it become useless and so does my iMac.

    Adobe, i think you clearly have a RAM management bug here. Come on, give us some responses!

    What I'm forced to do, if I have Sync occurring, is to run Task Manager (WIndows 10) with the Memory Pane open in a separate window, monitoring the memory usage graph.   The curve slowly edges upward towards 100% usage while syncing.  When it gets to nearly 100% usage, I completely shut down Lightroom 8.0 and wait for the memory curve to come back down to normal (about five minutes), then restart Lightroom.

    Memory overflow does not happen if I'm not syncing.

    This at least prevents my computer locking up.

    BUT WHAT THE HECK.  THIS IS NOT WHAT WE'RE PAYING FOR!

    If it was as simple as monitoring the sync and shutting the app down and restarting until it completed that would be fine.

    But I have caught up multiple times and each time:

    • The next time I restart it tries to re-sync a thousand or more pictures (10-20%).  It changes each time and shows them as "sync errors" until it catches up
    • And more importantly, changes I am making on my local library and changes I am making on the mobile copies are not syncing to each other anymore even once the sync is caught up and complete.

    This both renders the mobile apps useless and the memory link is making it impossible to use the local app too.

    How do we get support?

      Hi,

      I’ve been having the same issue with lightroom classic during September with previous 7.x version and now same problem with version 8. When syncing photos, it runs for a period until the program becomes unresponsive.  I’ve tried leaving it overnight, pausing and restarting the sync. Previously when sync has been stuck on a handful of photos I’ve deleted the sync.lrdata, which is a refresh of the sync. But this hasn’t helped this time.  Its got some crazy number of photos to sync

      It slowly consumes all the available memory until program becomes unresponsive and locks. It evens commits double the available memory in the PC! I can’t sync any changes I’ve made on the mobile device as it’s stuck in this loop.

      Please help Adobe

        Still the same even with last updates & co. I've start to tweet Adobe with reference to this topic (found messages @ngcreation) : we should all do the same, in public space. We have chosen their solutions, integrate it to our workflows, pay every month for this, with cloud services... For some of us like me, this is our working tool. Adobe not answering starting to be a real mess. Sahil.Chawla please said something prouve us Adobe have a little care for us.

        I have had this same issue since late September 2018 (not syncing and running up memory and crashing with not update to mobile)  Contacted Adobe Customer Service through chats who kept giving me same answer (is your version up to date), then I asked them to solve problem to which they set up three scheduled phone calls, including one at 11:30 pm and 8:30 am on weekends and then failed to even call. Adobe does not care and does not seem to care to fix this systemic problem as it just started all of a sudden (syncing just fine and then one day not).

        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!

          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.

            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.

              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.

                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.

                  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.

                    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.

                      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.

                      Same here, after rebuilding sync data.
                      It use all of my 64GB memory and more than 100GB on disk, all cleaned after a reboot.
