My environment:
kubernetes:1.24.17 (3 masters and 1 worker)
etcd and kube-apiserver run as pod in my cluster.
It runs well when all of 3 masters are 3.10.0-1160.99.1.el7.x86_64 kernel version;
I upgraded one master's kernel version to 5.4.277-1.el7.elrepo.x86_64(delete this node—>upgrade kernel version—>join the cluster)
this master's kube-apiserver runs well within the first hour, then it begins restarting and make etcd restarting, Besides, kube-apiserver makes the node stuck, after mv kube-apiserver.yaml from /etc/kubernets/manifests to somewhere else ,my node becomes normal.
I can't figure out what happened to my apiserver, any help would be appreciate.
The following is the related logs of kube-apiserver.
