Question

Constantly Saving XMP data

Wondering if anyone experiences this issue with Lightroom Classic on Mac OS.

 

I have a catelogue containing around 376,000 images. Recently I've noticed that Lightroom Classic will report it's 'Saving XMP for ñ photo' starting with the total number of images in the catalogue and running that number down as it goes.

 

The XMP data hasn't changed for photos so I don't know why lightroom is trying to save the XMP again for every image, but unfortunatly I can't let the programme run and complete this task as it just keeps eating up more and more memory as it goes on, eventually locking up and freezing. The last time I looked it was consuming 96GB of memory, my MacBook Pro M1 only has 16GB. 

 

Of course I can quit Lrc and I get a warning saying it hasn't finished writing the XMP data but it's ok and Lrc will continue the task next time it's launched. 

 

The problem is, due to the memory leak, the app never finishes the task.

 

Has anyone else seen this?

 

Running 14.1 now, but issue was on previous version also, on Mac OS 15.1 and 15.1.1 on an M1 Macbook Pro.

    If you have cloud sync enabled (i.e. cloud icon at top right corner of UI), then check whetter 'Pausing' it helps.

    Long standing problem that has yet to be resolved.   It seems to have several presentations but I suspect they all stem from the same root cause.  

    In my case, some percentage of my images can never get to a matched metadata state.  If I Read metadata from disk the mismatch icon goes off for a few seconds then comes right back on;.  If I Save metadata to disk the same thing happens.  Due to this I cannot use the Automatically save metadata to disk option as it will never finish for as soon as it writes the metadata to disk, it detects a mismatach and the same image goes right back into the queue to process.
