Occasionally, when looking at htop, I'll see my CPU spiking to 100%.
However, when I sort my running processes by CPU utilization, they don't sum to 100%. They don't even come close.
What "hidden" processes are running that are consuming my CPU? Can I see them?
Note that I'm still finding this to be the case, even though I modified htop's settings to display all threads and to not hide kernel threads.
