Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of WebSphere Application Server   *
  *                  V6.1                                        *
  ****************************************************************
  * PROBLEM DESCRIPTION: Inconsistent RMF workload activity      *
  *                      report queue times are being reported   *
  *                      for inbound http requests.              *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  An error was found in the determination of the WLM arrival time
  for http requests. The arrival time was subject to including
  network delays as the timestamp was being captured after
  reading the first inbound fragment and not being updated if
  multiple inbound fragments were received prior to queuing the
  work to WLM. This would result in incorrect and elongated queue
  times.
  

Problem conclusion

• The arrival time was changed to use the timestamp from the
  last inbound fragment received prior to queuing the request to
  WLM. This will reflect a more accurate queue time. This may
  result in a reduced queue time reported when multiple http
  inbound request fragments are received.
