Error description

• WebSphere Applicaiton Server 8.5.5.  Intelligent Managerment.
  
  If the Intelligent Management Application Placement Controller
  (APC) is running on a node, along with multiple members of
  dynamic clusters, the node will not go into Maintenance Mode
  (MM).
  
  The admin console will show that MM is being applied for more
  than 10 minutes, and eventually will fail to put the node into
  MM.
  
  This error will be put in the SystemOut.log file:
  
  
  NodeGroupXDUt E   NGRP0009E: Error invoking setMaintenanceMode
  on node YOUR_NODE_NAME, newValue: true leaveProcessesRunning:

  ****************************************************************
  When setting Node in maintenance mode, the list of servers
  which need to be placed in maintenance was incorrect. This
  caused the Node not to go into maintenance mode as all the
  servers could not go in to maintenance mode.
  

Problem conclusion

• The code is fixed to properly create servers list that needs
  to be moved to maintenance mode. The fix for this APAR is
  currently targeted for inclusion in the fix pack 8.5.5.5
