100% CPU load on all cores and heavy cache read (~300 mb/s)


Recommended Posts



For many months, I've had an issue with my server having 100% CPU load that I've been unable to troubleshoot since it begun, and this is why I'm finally posting here. Netdata reports high iowait when these spikes are happening. Bios is up to date, File integrity is not used in the system. I've removed every unused docker, reduced my ram usage by 10%, and still, it is happening again, but less often (it was every fifteen minutes, now it's once a day). I've tried many times tracing it down with iotop / htop, but I have not been able to find the culprit. When it happens, I noticed that cache drive read speed is really high (more than 300 mb/s).


I hope someone can help me figure it out, thank you for your time.
