  *                  Server                                      *
  *                  using stuck connection support with         *

  * PROBLEM DESCRIPTION: The averaging of duration times was     *
  *                      using more values then expected causing *
  *                      the averaged value to be less           *
  *                      responsive                              *

  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The averaging of duration times is configurable to use x number
  of values.   Since more values were being used to calculate the
  average, when the duration times changed, it take longer to
  detect the database is slowing down or stuck.
  

Problem conclusion

• The averaging of duration times is now using the configured
  value.
