k8s 部署mysql wanging （Aborted connection）信息？

k8s部署mysql，
BJ101856-1:/mnt/c$ k -n mcd-m8-infra get svc mariadb-galera
NAME             TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)     AGE
mariadb-galera   ClusterIP   10.100.205.168   <none>        13306/TCP   5h43m
打开mariadb-galera 服务，mysql报很多Aborted connection 信息，看host都是10.244.0.0类似网段。关闭mariadb-galera服务，报警消失。 statefulset里的探针是有密码的。

请大神们帮分析一下。是什么原因。
