warming listener never goes to active state

[zhangbo1882]

I use istiod(1.10) as the control plane to configure envoy (1.18.4).
There is a listener 0.0.0.0:8443. There are several filter chain which use server_name as the filter match in the same listener.
Someday, after istiod push a new filter chain in listener 0.0.0.0:8443, the listener becomes warming state and never goes to active state again. I enable the debug log and see that envoy has received the rds done message and notify Listener-local-init-manager. But Listener-local-init-manager never notify Listener-local-init-watchers so that inPlaceFilterChainUpdate is never called to move the warming state to active.

It seesm that #19262 has the similar issue for warming cluster.

From config dump we can see that the route object is there.

"version_info": "2023-03-03T06:46:42Z/122786",
"route_config": {
  "@type": "type.googleapis.com/envoy.config.route.v3.RouteConfiguration",
  "name": "https.443.bozhangtest10cont-https-443.bozhangtest10cont.bozhangtest1-pre-production-1",
  "virtual_hosts": [
   ...
]
},
