Lightroom: Running out of hard drive space (Mac)

I've recently upgraded my OS to 10.12.4 (Mac) and I'm noticing very odd behaviors in my Lightroom (2015.10 release).

While working in Lightroom, I keep running out of hard drive space, even though I have over 400GB free. It seems to continuously write data to my hard drive. I don't notice it, until I start getting system notifications that I have no space left on my hard drive. After I quit Lightroom, the space instantly frees up.

This happened twice since I upgraded a couple of weeks ago. I also upgraded my Lightroom at around the same time. I've never had those issues before

Is anyone else seeing these issues?

No. I use the same MacOS and Lightroom versions, have less free space on my internal disk than you have and do not see any issues. Could it be that you have some incompatible plugin at work? See if disabling all plugins makes a difference.

Can you include more information about catalog and operations you are doing ?
Are videos involved ? Are you trying to play/preview Slideshows ?

Hi Rahul,

I'm mostly working in Develop or Library modes, in 1 catalog. No slideshows or videos. I've attached a screenshot showing all of my active plugins. Let me know if anything else would help troubleshoot it. 
Also, yesterday I noticed that Lightroom was creating copies of my master files in their original location. See the second attached screenshot. All the files with timestamps in them are created by Lightroom.  There are only 3 original files in this list. At one point, Lightroom even lost the file I was working on in Develop module: in the middle of editing, I got an error message saying that the file wasn't found. That's how I discovered these multiple duplicates, but also the original JPEG was missing in that case. 

I've quit and restarted Lightroom since I noticed that, but nothing changed. Let me know if you'd like me to create a separate post for that. I haven't seen this happen with my RAW files in any other folders before. 

Thanks in advance,

That doesn't look like something Lightroom's doing. That looks more like you've got some backup program running in the background.

What are you doing when this is happening? Importing? Working in Develop? If you go to Catalog Settings > Metadata tab, are you set to write metadata back to the files?

I do use a backup program, Crashplan, but it doesn't show any crazy activity and it backs up from my laptop to the cloud. So no local changes are written. 
As for the metadata, the first 3 boxes in the Editing section are checked. The rest are unchecked.

Is Photoshop also running when this happens? There was an issue with the 2017.1 release that affected scratch disk usage. If you are running Photoshop, make sure you update to 2017.1.1.

I think it was running on at least one of these occasions - I usually run them in parallel. But can't be sure about all of these. I see that there is an update now from yesterday (?), so I just installed it. We'll see what happens.
