You have a few problems.
First, if using IE 11, switch to FireFox or Chrome. There is an issue with IE 11.
Next, it looks like your media was once scanned, identified, and loaded only to disappear. It looks like it’s out on a network drive.
PMS doesn’t like it when it goes to look for media and it’s not there.
Also, what you’re seeing is probably because it’s trying to find the missing media and, while looking for it, is using the default ‘hourly’ library update interval. What happens in this case is a snowball effect. It gets more and more behind but will never catch up because the media is constantly coming back and then disappearing again (PMS detects changes such as that automatically).
In your log files, I see unending lists of:

Please notice where it says reusing. This tells us it already knew about it but now has ‘found it again’. Why? is the question.
I suggest a few changes to your Settings - Server - Library in addition to the administrative task you must perform to ensure your media doesn’t “disconnect”.
If the Plex/Web UI is 100% locked up, you will need to stop PMS, go into the AppData and find “Preferences.xml”. When you find it, you need to delete it.
When you restart PMS, it will not have the basic EULA acceptance flag (that you did) and wait for you to accept again. Opening your browser to the command port (http://127.0.0.1:32400/web) in Chrome or FireFox (IE 11 is a a known issue) will put you back in control to make the changes I show below.
I then recommend you take a good look at how media is named. The better it is named, the faster it’s matched. I can match 7000+ Television episodes in a couple hours. I can match 90,000 episodes (796 Series) in 21 hours if this helps you understand how quickly it should run. From what I can see, you have a good grasp on it and mostly in place. Something must have slipped by.
If you have multiple Library sections, Update 1 section at a time AFTER you have confirmed your network storage isn’t going to keep dropping out on you.
