Hi, I observed the following stack trace while deploying an application in Stratos. Here are the steps that I did.
1. Deploy network partition, policies, application. 2. Wait until application is active 3. Undeploy the application. 4. Restart Stratos 5. Deploy the application At this point following error is thrown from Stratos. I've created JIRA at [1] to track this.
