APAR status

• Closed as program error.

Error description

• A core dump occurred with the XIV binary that is part of the
  Spectrum Control data collector service. The core dump was
  noted in the the AIX errpt, but the core file referenced was
  not available for analysis. It was automatically removed as
  part of performance monitoring data processing. The directory
  for that sample no longer existed.
