Increased CPU usage after Docker upgrade (runc init)

Recently, I’ve upgraded Docker from 18 to 20.10.13 and I noticed increased CPU usage caused probably by runc init process that appears every few seconds in processes with ~15-20% CPU usage. I’m running same docker version on much smaller server and CPU usage there as much lower.

Any ideas how to find a cause? The presented CPU usage is during with ~6 idle containers. I’ve tried to reboot the server, but it didn’t help.

Edit: Okay, I reverted docker to previous version, together with containerd, and runc. It works fine now. I think I will keep it as it is.
