RAM usage/memory leak on Mac OS

Hi there,

 

I've been having this problem for about half a year now. I thought it would get fixed in the recent 13.2 LRC update, but that wasn't the case.

 

So what happens is that my RAM fills up when LRC is idling for some time. I work on LRC then move to another task, put the iMac in sleep mode, wake it up again the next day and at some point memory usage goes from around 7 GB to 150 GB (!).

 

Looks like a memory leak to me. Pls Adobe, fix this.

 

Running Mac OS 14.3.1.

 

Thanks

    Contacted Adobe Support. They identified two issues:

     

    1. The performance settings were not set to provide maxium performance. They have been updated. See image below.

     

     

    2. LrC continuiously syncing in the background due to a new sync version released by Adobe. After pausing the sync, the memory usage that was rapdily being clocked up in the background stopped.

     

    Additionally, 

     

    3. Several of my photos' originals were lost in the past and were previously synced to the Cloud. LrC sync was continuously trying to sync these photos and therefore the sync was stuck. I removed all Collections that were being synced. This must have also helped bring the memory uage under control. 

     

    See the current memory usage after an hour's of heavy editing (including AI edits) below - it appears more reasonable and under control.

    Been trying to find a solution on forums but couldn't so opted to post it here:

     

    - LrC is memory usage ~74gb (has exceeded 80gb at times as well)

    - LrC still working but quite slow (basic edits are even taking time)

    - Completely erased MacOS and installed a fresh copy of Sonoma 14.6.1 (current version), and only softwares I have installed are LrC and Outlook at present besides the default apps and software

    - Have also tried to upgrade MacOS to Sequoia Beta 15.1, but even that did not make any difference, hence decided to erase MacOS and installed the fresh Sonoma as noted above

    See attached screenshot from Activity Monitor. 

     

     

    Questions:

    1. Is this normal (in the nearly decade of LrC usage, I have not quite experiecned anything like this)
    2. Can this be fixed?
    3. Please share a solution

      This definitely helped. I had errors in Sync Activity (Preferences->Lightroom sync). After clearing them, memory usage decreased and responsiveness of Lightroom Classic increased. I now keep cloud sync paused unless I need it.

        I think I've found a clue about the memory leak. If I leave LRC in Develop mode when I exit, it starts up in Develop mode and leaks memory. But if I exit in Library mode, it starts up in Library mode and doesn't leak memory, even if I leave it sitting in Develop mode while I run an errand or something. So, to reiterate, putting it in Library mode before quitting is my workaround.

        Good catch. I'll report to QE.

          It would be helpful if you all posted a copy of the LrC 'System Info'. This can be obtained from the Help > System Info menu item. Use the built-in 'Copy' button. I've attached screenshot of the dialog for info.

           

          Note that the 'System Info' is most useful if captured when your memory useage reaches a high level rather then directly after relaunching LrC.

            'System Info' is indicating that the application and GPU are using less than 6GB of memory. Try temporarily disabling the Topaz plug-in to see whether it helps the amount of memory being consumed when computer is idle.

            I have the same problem. I'm running LRC 13.2 on an Intel Imac Pro with Sonoma 14.2.1. I started LRC about 40 minutes ago, then ran an errand. When I got back the memory usage was 33 GB (on a 32-GB machine). Now, five minutes later, after having done nothing in LRC, the memory usage is up to 37.5 GB. The only workaround I'm aware of is to process a few images, then quit and restart LRC.

            There also seems to be a correlation between how much RAM you have installed and RAM used by LRC. In above mentioned case RAM usage went up to 150GB with 64GB installed.

            I'm on 32GB total RAM now and LRC would only use around 70GB now. Obviously still a memory leak, but I thought it might be helpful to mention this.
