Glad you posted this. Let me chime in and say that Lightroom Classic is eating all my Ram on my Windows 10 PC! I coincidentally put in a new Graphic card yesterday, having 12 GB instead of 6 GB GPU memory, but I am not sure if this has anything to do with the problem. I would not think so. In my case, if I work with Lightroom Classic for about an hour or more, my PC lags and freezes to the point that it is unusable. Looking in Task Manager when this happens, I see that Lightroom has laid claim to over 15 GB of the available motherboard RAM (I have 32 GB installed, but at this point, the total motherboard RAM usage is up near 100%).

Adobe, what is going on here? Doesn't Lightroom Classic ever release memory when it moves on to the next image or next task? Or do I have to restart Lightroom every half hour? I understand from others that Lightroom is apparently not very good at releasing memory again, but if this is true, then this might be something important to improve soon.

I have the same issue. I have a MacBook Prom M3 with 36 GB of Ram and I find that as I keep LR open, it starts to use more and more memory until I run out of application memory and am forced to quit. I  can't believe that Adobe has not come up with a fix for this. It seems that I can only work in LR if no other programs are running on my computer and even then I eventually get the out of memory window.

If you have cloud sync enabled, then try pausing. it. If pausing cloud sync helps, then the underlying issue is that some files are stuck in th sync queue.

Thanks I will take a look at that.

I think I have some sync errors. I've paused the sync and am monitoring the Activity Monitor to see what happens. How would I rectify if files are stuck in the queue?

I'm having the same issue, with LR hogging so much memory that I get warnings from the OS. Using MacBookPro with M2Pro chip and 64 gb RAM. I will pause sync and see if the situation is remedied. Thx
