After the routing configuration update, some requests in Apache APISIX are still routed to the old upstream service

[CCTV-six]

Current Behavior

In APISIX, when an administrator updates the routing configuration (such as changing the upstream service address or removing a certain upstream service), theoretically all requests through APISIX should follow the new configuration. However, in practical operation, there may be situations where some requests are still routed to the old upstream service,

Expected Behavior

Steps to Reproduce

1. Install and start the APISIX cluster (at least two nodes).
2. Create a routing rule that specifies an upstream service.
3. Send requests to APISIX to ensure that they are correctly routed to upstream services.
4. Update routing rules, such as changing the upstream service address or removing the upstream service.
5. Immediately send new requests to APISIX and observe if all requests follow the new routing rules.

Environment
