Please provide the links to the odroid forum discussion
You can also try to compile the following test:
https://gist.github.com/tosiara/3c9739744b6dd17d8f1ea3c0d99d8b9d
gcc threads.c -o threads -lpthread
Run it as:
./threads 8
Does it cause shutdown?

I'm running 8 cameras (3 streaming RTSP @ 5 frames/sec, 3 snapshot at
5/sec) on a Rock64 4GB (quad core ARM 1.3GHZ).? I initially had issues
with CPU usage when running 4.2.2, but eventually brought it in line
with the usage I saw running 4.1.1. However, due to the new web server
in 4.2.2 not being browser friendly with more than 6 cameras, I
abandoned it, and went back to 4.1.1.
I'm currently seeing usage numbers between 140% and 170%, until I
connect to the camera web page.

Check your CPU usage without anything connecting to the camera web
page.? If it's still high, then it must be a Motion configuration issue.

This might be a little bit late, but check out this one:

Looks like this guy has successfully solved similar problem.
