kernel process (PID 0) constant 50% CPU usage

[Bernard Mentink]

Hi all,

Noticed this CPU usage on the kernel process the last few days .... I don't know if it has anything to do with installing some iocage jails, as that was my last activity on the server.
I have turned off the jails, but no help ..

Maybe related, but I noticed that on a reboot of the server it did not get a DNS resolver on boot .... I had to add "nameserver 192.168.178.1" (my router) to /etc/resolve.conf

Any help in debugging this appreciated ..

Were you able to resolve this?

If it's still going on, please run top -m io.

Hi, nope still going on.

I did as you asked, and only noticed the following processes that briefly went to 100% then disappeared again:

mysql,
http,
python3-6

One or the other appear for a second then goes away ..

Update: A rebbot of the server fixed it ... will see if it happens again ... it's a mystery ..
