CPU load of 100% is fairly high. You might consider running fewer programs on your Pi, or upgrading your Pi to a faster version such as the Pi 2.
I have a Pi 3B+. When i check the cpu load, it’s not 100%. Graphs 1090 never shows a load that high. Is that just for 1 core? Or is the CPU load something else entirely different?
Also, feeding 2 sites with just the one Pi. Shouldn’t i see the error for both sites since it’s the same Pi?
I’m interested in this question also. I’m running an RPi Zero; I have turned off A/C decoding and set low-cpu to yes. Yet I’m getting the CPU load anomaly. When I log in via SSH and run top, this is what it reports:
