I'm in the process of moving and consolidating from multiple machines running Aperature, iPhoto, and Photos to get all pictures into one filing and catalog system. There is about 2.6gb total of pictures and some 100,000 including duplicate images.

The catalog in question has 38,000 images & I wanted to copy it into an empty catalog (create a master).

The issue that I'm having is that it seems to be hung with "Import photos and videos from Catalog Updating Stacks". It's been in that status for at least 24 hours at this point. Lightroom is still using the CPU but very little action seems to be occurring.

I'm at the point of doing a "quit or force close" on LR but would rather not if this will complete

Suggestions are appreciated.
 
I'd probably force quit and start over. The first thing that you need to do is check each catalog for completeness and resolve all missing images issues if there are any.
The next step would be to find the catalog that has the largest number of images and make that the master. (You do not need to start with an empty catalog) Merging everything else into the catalog with the most images means less work over all. If you don't like the name of the largest catalog file, you can rename it and the accompanying Preview Folder. When you import be sure to include the existing previews so that you do not need to rebuild previews.
Before you start merging, make sure that you have enough freespace on the primary drive and that images from merged catalog won't be filling up that primary drive and sucking away all of the used free space. LR will use the freespace to create temporary files during the import process. I'd try to start with 200-300GB free on the primary drive. If LR runs out of freespace or RAM it could hang. Hopefully you have at least 16GB of RAM and at least 4 cores. LR will not like is the system starts moving memory to the Swapfile and LR needs it back.
 
For some reason LR often gets buggy for me, then I reset preferences and the problem goes away. On several occasions that has not worked and I have deleted LR and reinstalled it and that solved the problem.
