      2. Or, use a more "stateless" session manager suitable for use with Deployments, e.g. hotrod-session-management

    Description

      This is a follow-up issue for JBEAP-22064 to track the issue being discussed there, that scale down of a distributable web app causes small data leaks for DeploymentConfig.

      1. Setup distributable application on OCP using DeploymentConfig
      2. Generate Load using jmeter
      3. Scale down and up in loop e.g. each 3 minutes
      4. After load ended there are some sessions left (should be 0)

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
