It seems that kubernetes/kubernetes#100376 was not fixing the issue.

  • current v1.18.20-lts.0~2 have this issue.

Workaround:

#!/bin/bash
echo `date`: "check  kubelet ... "
 
output=$(journalctl -xu kubelet --since="5 m ago" --no-pager |& grep "use of closed network connection")
if [[ $? != 0 ]]; then
  echo "Error not found in logs"
elif [[ $output ]]; then
  echo "Restart kubelet"
  systemctl restart kubelet
  echo "Hi, kubelet reboot time $(date)"
fi
