What version of gRPC-Java are you using?

v1.67.1

What is your environment?

jdk 21 eclipse temurin

What did you expect to see?

We are using istio version 1.20.1 and with this we are using grpc-proxyless setup for client side load balancing with grpc-xds in production in a multi-cluster environment. This setup has been working fine up until now.

Our service connects to several grpc targets which are present in other cluster, so we expect the routing is done correctly to each services as they have different service endpoints.

What did you see instead?

We see that the request is mixing between the services which are present in other cluster.

We were receiving status code as 12, when we turned on the debug logs and tried investigating further, we saw that the requests that were supposed to go on service A, few of the request were going to service B and vice versa. We are not sure why this is happening and it is not easier to reproduce as well as it happens randomly on different pods and persists for a longer time.

Lets say when a call to service A is going to service B, we identified the IP and killed that pod. Post that it picked up another IP of service B and started sending it request.

Since there were lots of changes related to load-balancing and also XDS fallback where XDS client was seaprated for each target, I am suspecting some issues in these modules.

We verified by reverting and upgrading multiple times that this is only happening for version > 1.66

it starts calling dmm-grpc.dmm-prod.svc.cluster.local for the same IP, while as you can see both the services are presnet in different namespaces (although in the same cluster). Also the since the server is responding with status code 12 hence it is live and the IP is not re-assigned to the other service or anything.

The same is not happening for the version 1.66

Istio is broken with gRPC Java 1.67+: istio/istio#53532 . I wonder if it can send responses on the wrong stream, in addition to closing other streams. (... although the resource names would also have to be wrong...)
