APAR status

  • Closed as program error.

Error description

  • Amqrrmfa processes of a queue manager create redundant opens
    among each other, whenever one of them reinitializes.
    Whenever a repository manager reinitializes,
    an error AMQ9448 is logged.
    This is related to IT24388.
    

Local fix

  • Reset affected amqrrmfa processes, using amqrfdm tool
    with option -r.
    

Problem summary

  • During initialization amqrrmfa processes created always IPC
    connections to all other amqrrmfa process instances associated
    with the queue manager, without accounting for any existing
    IPC connections to these processes. The other processes also
    established IPC connections to this amqrrmfa process, again
    without accounting for existing IPC connections.
    

Problem conclusion

  • Code was changed to check, before creating a new connection,
    for a still valid connection. Now a new connection is created
    only when there is no longer a valid connection.
    Any preexisting invalid one will now be closed.
    

Temporary fix
