   Change team found CSQX053E is issued because of the top message
  on the SYSTEM.CLUSTER.COMMAND.QUEUE (SCCQ) which is a resume
  cluster command for the cluster xxxx. Under certain
  circumstances the command causes a channel to be restarted, but
  because the channel is already started message CSQX514E is
  issued and the repository manager stops because of the errors.
  

Local fix

• Make the channel inactive or stop it. If this does not
  work, remove the top message from the SCCQ.

  ****************************************************************
  The RESUME command may attempt to start associated cluster
  channels if the queue manager has previously been suspended with
  MODE(FORCE) from all other clusters it is a member of. In the
  case where the channel being started is already in a non-stopped
  state, the start will fail as the state shows it is already in
  use, shown by CSQX514E. As this error is not expected, the
  resume processing will fail and a snap dump will be taken. This
  error also causes the cluster repository manager to stop.
  

Problem conclusion

• Processing for resuming the queue managers membership in the
  cluster has been changed to handle the case where the cluster
  channel is already in use, if it attempts to start the channel.
  This stops the snap dump from being taken and the cluster
  repository manager from stopping in this case.
