**Hi Community,**

I am working on deploying the `kernel-idgenerator-service`. Previously, I was facing `ModuleNotFoundException` errors related to Ceylon, but I have resolved that by correctly adding the required `regproc-reprocessor-ceylon-cache-repo`.

**Current Status:** The logs are now clean (no exceptions), and the `HttpServerVerticle` reports as “Deployed”. However, I cannot reach the service from other internal pods (e.g., `id-repo-identity-service`).

**The Issue:** When I start the pod, the logs initialize and reach the point where `HttpServerVerticle` and `IDGeneratorVertxApplication` start, but then the logs stop moving. When I try to hit the endpoint `http://kernel-idgenerator-service:8080/v1/idgenerator/uin` from another pod, the request times out or fails to connect.  
**Logs:** Here is the sequence :

_logs.._

**My Observations:**

1. The `VidPoolCheckerVerticle` seems to initialize successfully.

2. The `HttpServerVerticle` is marked as deployed.

3. However, `curl` commands to port 8080 fail.

**Question:** Does the log message `"Service will be started after pooling"` imply that the HTTP server is holding traffic until the UIN/VID pool is fully populated? If the pool is empty or cannot connect to the DB/Queue, will the service remain unreachable on port 8080, or should it still respond to health checks?

Any insights on why the service would be unreachable despite these successful deployment logs would be helpful.

**Environment:**

- **Platform:** OpenShift / Kubernetes

- **Service:** kernel-idgenerator-service

- **Caller:** id-repo-identity-service

Hi @Tony_Stark,

To better understand the deployment and address your query effectively, we need a few more details from your side:

1. Could you please confirm the version that has been deployed?
2. We did not observe any errors in the logs you shared. However, we still have a few questions, and our team will review them to clarify your concerns.

Looking forward to your response.

Thanks and regards,  
Praful Rakhade
