  ****************************************************************
  The cluster maintenance routine finds a queue which has its
  refresh bit on but has no subscriptions for that queue. This can
  occur if the queue exists in a cluster which has since been
  removed. The maintenance routine tries to remake the
  subscriptions, however it finds that there are no longer any
  full repositories for that cluster and this causes the
  repository manager to terminate.
  

Problem conclusion

• The cluster maintenance routine now tolerates the condition
  where no full repositories are found for a given cluster,
  allowing the repository manager to continue executing after
  issuing the FFST to report the missing subscription.
