We are running payara/micro:6.2024.7-jdk21 with our application in a Kubernetes cluster managed by DigitalOcean.

Problem:
Randomly, port 8080 does not open inside the pod. As a result, the readiness probe fails, and the container restarts. After the restart, everything works as expected. This happens completely randomly. It occurs at a stage when no service is yet routing traffic to the pod. The service switches between blue/green only after both pods are functional.

HPA is set to a minimum of 2 replicas.

We deploy using a blue/green deployment strategy.

Tests performed: • Immediately after starting the container, we run netstat -tuln. It shows no open ports. • Once Payara Micro starts up, we can see ports 8080 and 6900. Occasionally, 8080 is missing. • No problematic logs, except for:

SEVERE: Error adding HttpProbes. NetworkListener http-listeners GrizzlyProxy is NULL.

Question:

Has anyone encountered a similar issue where Payara Micro randomly does not open port 8080 on startup? What could be the possible causes and solutions?

• kubernetes
• payara

1 Answer 1

The exceptions you posted are ugly but can be ignored. They happen during cleanup phase after deployment, because the internal JDK field loaderRef was removed in Java 11, and the internal method clearProperties also doesn't exist on BeanELResolver anymore. Payara should fix this, but it doesn't do any harm, Payara ignores the exception and continues as normal.

I think the message SEVERE: Error adding HttpProbes. NetworkListener http-listeners GrizzlyProxy is NULL. is also harmless. It's probably logged because the HTTPS listener is not enabled and therefore is NULL.

None of the errors explain why the Payara Micro doesn't binds to the 8080 port.
