Memory leak in LR Classic CC on Mac El Capitan

I am using the new Lightroom Classic CC on a mac running El Capitan. Lightroom is up to date according to the Creative Cloud window. However, I can barely use it anymore because it constantly crashes my whole system - I am constantly getting windows saying my system is out of application memory. This only happens when I run LR, not any other apps. Activity Monitor shows LR's memory usage constantly climbing until it crashes within a few minutes of starting it. 

I went through troubleshooting with an Adobe tech support person a couple weeks ago and they had me share my screen with them and they changed the permissions on a Library file, which seemed to fix it for a couple days, but now it is back to not working. I don't have time to do a chat with them during business hours this week so I'm hoping for some other tips here that I could try on my own  (for instance, I could have changed the permissions on that folder myself if they had told me to, rather than screen-sharing). 

I suspect this has something to do with me having added a lot more photos to my Library. A month or so ago I had about 20,000 photos in there. I decided to merge some old libraries together and now I have 50,000+ and ever since then it has been really struggling. It worked ok for a few days after the merge so I didn't immediately think it had messed things up, but after that it started freezing. It may have something to do with trying to sync all those photos. However, Adobe tech support claims it should work fine with that many photos. I tried pausing sync and the memory usage kept climbing until it crashed, so maybe it isn't just the syncing that's the issue. 

I have the catalog file on my laptop itself but the photos on an external drive which I keep plugged in whenever I'm using LR.

(Its a good thing I have LRM on my iPad - I'm doing everything there for now since I can't use LR on my computer with this memory leak issue.)

Jessica, 

When you say you are up to date according to the CC App that tells us very little. Please go to your Lightroom interface and navigate to Help>System Info...  Once there, copy the exact complete version number and paste it in a comment here. We should determine exactly what version you have installed.

Jessica,

When you say " tried pausing sync and the memory usage kept climbing until it crashed," does this happen when you pause sync explicitly? Will the memory usage come down when sync is resumed ?
Along with the system info, could you please tell me how many images are you trying to sync ?

I have around 45000 photos in All Synced Photos, and about 55000 photos total in my library. I’m not sure how many are remaining actively trying to sync.

I tried yesterday right before posting explicitly pausing sync and then watching Activity Monitor, and it showed the LR usage continue to climb until the system crashed. However, I just tried that again right now and the memory usage did go down -but now is climbing again. Hasn’t crashed yet but may after awhile.

It seems like it is struggling to access some collections. When I click on certain collections, especially from LRM, half the time I just get a grey screen that says “loading”.

I am not sure if sync or collections from LRM is the issue. Those things are most noticeable to me because at the moment, that’s the only thing I really want it to do - keep syncing and show me photo collections of synced photos.
