<p>I am trying to run a tomcat instance on an EKS cluster to connect to activeMQ, however, the pod continues to crash with error javax.jms.JMSException: Stopped.</p>

<p>I have tried recreating the pod and increasing the resources for the pod but I am unable to determine the root-cause or possible cause for the crash.</p>

</code></pre>

<p>Looking at the stack trace, it seems that there is readiness probe and/or liveness probe configured to hit Spring Boot actuator's health endpoint and the health check includes verifying JMS connectivity (to ActiveMQ).</p>

<p>I'll suggest checking in the application configuration and disabling</p>

<pre><code>management.health.jms.enabled=false
</code></pre>

<p>...in case that it is enabled (<code>true</code>).</p>

<p>Alternatively, disable/remove any readiness and liveness <a href="https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-probes" rel="nofollow noreferrer">probes</a>.</p>

<p>Upon some actual activity, that may allow the application to error out and log better message(s) to help you troubleshoot the problem.</p>
