APAR status

• Closed as program error.

Error description

• For some cases, the ncp_model process uses excessive a mounts of
  memory which in turn for large topologies can lead up to
  ncp_model crashing when reaching 4Gb.
  

Local fix

• N/A

  * PROBLEM DESCRIPTION:                                         *
  * The ncp_model process was using more memory than it needed   *
  * to which in extreme cases resulted in it reaching the 32 bit *
  * application limit of 4GB and failing.                        *

Problem conclusion

• Code changes were made to reduce the ncp_model process's memory
  consumption which should now be comparable with that of the
  ncp_disco process in large environments.
