From top command screenshots, ksoftirqd and iptables processes seem to be consuming a lot of resources (memory, CPU and swap) and had been running for more than 100 hours.
There’s a known bug in the iptables of some Linux distributions: Advanced Options / Configuration | K3s
The workaround is to tell K3s to use its bundled version of iptables by starting K3s with the --prefer-bundled-bin option (you’ll need to edit the file /etc/systemd/system/k3s.service and restart all the nodes), or by uninstalling the iptables/nftables packages from the operating system.
