Kubernetes version - 1.12.4 Docker version - 18.06.1-ce OS - CentOS Linux release 7.5.1804 (Core)
Everything is working fine, but when I restart kubelet service, we are getting below logs in kubelet logs, node status change to not-ready. It remains for next 3 minutes. We observed this on 1.11.x and 1.12.x, did not try yet 1.13.x. We are getting this issue on all k8s cluster nodes. There is no load on node(cpu/mem/iowait), all are fine.
