Problems with server, all cpu's pinned and crashing various containers.

I have had the same issue for the past couple of years. Before I get into everything here are the plugins installed as well as Unraid Version etc. 

Unraid Version: 6.12.10
Installed Plugins: Appdata Backup, CA AutoUpdate Applications, CA Dynamix Unlimited Width, CA Mover Tuning, Community Applications, Dynamix Active Streams, Dynamix Cache Directories, Dynamix Day/Night, Dynamix S3 Sleep, Dynamix System Temperature, Fix Custom Problems, GUI Links, Nvidia Driver, rclone, Tips and Tricks, Unassigned Devices, Unassigned Devices Plus, User Scripts. Virtual Machines Wake on Lan. 
Hardware: Dell r720xd

My server periodically puts all cpu threads at 99 percent and things are unresponsive for minutes at a time. This makes the GUI and my Plex server unresponsive during this time. Usually things will settle down and go back to normal eventually. 
 

This happens most often when I us Sonarr or Radarr to find content, nzbget does its thing and then content moves along, but when a lot of requests are thrown through either *arr application the server will eventually slow down to a crawl and then just stall completely. I usually can't navigate within Sonarr or Radarr and check on the GUI for Unraid and navigating there as well is either slow or goes nowhere. During this time if I am on the dashboard for Unraid I can see all of the CPU threads pinned at 99 percent. Eventually when things start working again the GUI for Unraid as well as any container is usable again until I go through making multiple requests to get more content where things just slow down again or completely freeze up. 

Hopefully someone can guide me in the right direction for a fix here. This server ran fine a little over a year ago. 

I have tried starting one container at a time to see if there is a particular container that is causing problems and honestly they can all be started without issue and run fine for sometime before a list gets pulled for either Sonarr and Radarr and then new content gets requested and things again can slow down again. Would love some help.
