Problem conclusion

• Added a batch mechanism for data collection, so that the larger
  switches can be used for performance monitoring by collecting
  the data in smaller chunks.  The fix for this APAR is targeted
  for the following maintenance package:

  The target dates for future refresh packs do not represent a
  formal commitment by IBM. The dates are subject to change
  without notice.
