WebSphere MQ for HP NonStop Server V5.3.1 fix pack 5.3.1.15
WebSphere MQ for HP NonStop Server V5.3.1 fix pack 5.3.1.16

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
