Research direction

Begin with the client-side internal_error 0x2 and the server log showing the connection faulted. Reproduce the bidirectional streaming RPC under the load test, then compare client and server logs to identify where the disconnection begins. Done means a confirmed cause and either a fix or documented troubleshooting guidance.
