jinjianming opened a new issue, #1855:
URL: https://github.com/apache/apisix-ingress-controller/issues/1855
### Issue description
Why does the Apisix ingress controller frequently request upstream of
Apisix, resulting in a large number of 404 requests on my Apisix;
```
2023-06-09T21:24:19+08:00 warn apisix/upstream.go:69 upstream not
found {"name": "default_js-design-server_3002_service", "url":
"http://js-apisix-admin.ingress-apisix.svc.cluster.local:9180/apisix/admin/upstreams/88c42dc3";,
"cluster": "default"}
2023-06-09T21:24:19+08:00 warn apisix/upstream.go:69 upstream not
found {"name": "default_js-design-server_50000_service", "url":
"http://js-apisix-admin.ingress-apisix.svc.cluster.local:9180/apisix/admin/upstreams/d8c6437f";,
"cluster": "default"}
```
Steps to Reproduce
```
kubectl apply -f svc.yaml
```
``` yaml

```
## i saw #1655 This issue is because ApisixRoute was not associated with
ApisixUpstream, and I correctly associated it. Why are there still many warnings
## As shown in the figure, there are many 404s in the log collection system,
which is very unfriendly
## Also, I see if there is any new progress on the issue #864, and I really
need this feature as well
## Because I have to configure apisixupstream for forwarding on GRPC
