Hey guys, yesterday I noticed the fans in the server started spinning up and down at regular intervals, so I looked at UnRaid's System Stats and saw that the CPU was spiking up every 8 seconds. From the dashboard, in the System Status, I can see that every 8 seconds, a random thread spikes to 100% usage and then goes down to 0%.
All the VMs are shutdown, and I also tried disabling Dockers completely but I am still getting the same result.
I also tried SSHing to the server and looking at "top", but I didn't see anything super suspicious, although I might need help on that front.
What steps should I take to debug this issue and determine what is the cause of those spikes (I assume that's not "normal") ?
Thanks !
