APAR status

• Closed as program error.

Error description

• If the Load utility generates lots of warnings (for example if
  the data being parsed is full of errors, truncations, or
  rejected records), the utility may perform very poorly.  This is
  because the Load utility opens its internal server-side message
  file using the O_SYNC flag which means writes to this internal
  server-side message file will block until all message data and
  file meta-data is written to disk. Since this data is not
  critical to the operation of the utility or management of the
  database, we will avoid opening the server-side message file
  using this O_SYNC flag.
  

Local fix

• You can specify the Load NOROWWARNINGS modifier to force the
  Load utility to avoid writing warning messages all together.
