APAR status

  • Closed as program error.

Error description

  • When queue handles are used by an Execution Group, for example
    in flows including MQ Nodes or during operation of the
    broker-wide listener, the handles are cached for future re-use
    to avoid the overhead of recreating the cached object.
    
    When a handle is disposed of either because it has become
    invalid or has been cleaned up due to idle processing the key
    object used to store the handle in the cache can be leaked.
