Last 2 weeks I have been running into this odd issue, running HA OS on an intel nuc type of mini PC and I have seen CPU jump to 60-100% for no apparent reason and a restart will fix it.
Not seeing anything in the logs, but Core cpu usage under the supervisor blade, this seems to be the issue.
Problem is I have no idea what is actually causing the spike.
How can I find if a process is running amok and what one is doing it?
