Pid 0 - kernel process. High CPU

[VitS]

Hi,

Using htop - I can see strange process: PID 0 by root kernel process

And it is jumping from 10 to 50 % usage.

I thought tat maybe someone process command and it still active, but checking with ( w ) - I found only myself and I have only one terminal opened.

In google I didn't found more about this process. So could You, please, explain me what this process is about and maybe how to stabilize it?

FreeBSD 12-0

Thank You,

The first PID is 1 and that's typically init(8). PID 0 is the kernel itself, not a process.

Process ID 0 can be naturally busy in various situations. File system activity can make the kernel busy, and so on.
