问题是什么
ks-console频繁重启，导致web页面无法访问
1、查看pod日志，无异常信息，最近一次pod日志如下
> kubesphere-console@3.0.0 serve /opt/kubesphere/console
> NODE_ENV=production node server/server.js
Dashboard app running at port 8000
<-- GET /kapis/monitoring.kubesphere.io/v1alpha3/namespaces/monolith/pods?cluster=default&ownerKind=ReplicaSet&labelSelector=app%3Dmonolith-web&resources_filter=monolith-web-7fb9f67cfc-xqrv7%24&metrics_filter=pod_cpu_usage%7Cpod_memory_usage_wo_cache%24 2024/03/20T13:55:01.864
2、使用kubectl命令describe ks-console 的pod，可以发现 存活探针探测8000端口超时
