    Problem Description
    When a Kafka business process runs in a clustered environment,
    the Kafka End Session Service can fail if execution switches to
    a different node than the one that initiated the business
    process.
    

Problem conclusion

  • Resolution Summary
    This issue occurs in clustered environments when the Kafka
    business process is initiated on one node and the End Session
    Service executes on a different node. The product has been
    updated to incorporate NullPointerException (NPE) handling and
    time-to-live (TTL)-based cleanup activities to reclaim resources
    
    after the business process completes, preventing errors during
    session termination.
