I have a server running on RancherOS. Recently, the server has been responding very slowly. When I run
top, I see values for “load average” around 30, which as far as I know is really high. However CPU usage is somewhere between 5% and 10%. Of the 16 GiB of RAM, around 6 GiB are used.
iotop also doesn’t show any significant hard disk usage.
I’m still having trouble completely understanding the architecture of RancherOS. Could it be that there is a process using a lot of CPU power in another container, so I cannot see it when I run
top in the
console container? How can I find out what is causing the high load?
