Radarr: Restarting Radarr from WebUI causes high CPU usage

[plexecutor]

Describe the bug
When manually restarting Radarr from the Web interface, the Radarr process begins consuming high amounts of CPU resources until the service is either manually restarted from the command line or the system is rebooted.

To Reproduce
Steps to reproduce the behavior:

1. Load the Radarr Web interface
2. Click on 'System' and then 'restart'
3. Observe server CPU usage via htop
4. See high CPU usage by Radarr indefinitely

Expected behavior
Radarr restarts and goes back to idle CPU usage

You're probably running this w/ a systemd service file, right? You probably just don't want to use the restart in the UI. If you have systemd setup one way, it'll probably lose track of the process. If you have it setup another way, it'll probably try to restart it itself. You probably want something like Restart=always and then from the UI, just shutdown instead and systemd will start it up.
