Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of QCF3.1 overflow protection. The *
  *                 changes are in the control region programs - *
  *                 the changes will be in effect after the APAR *
  *                 is applied and the control region is         *
  *                 restarted.                                   *
  ****************************************************************
  * PROBLEM DESCRIPTION: First the usage of the queues should be *
  *                      checked to set the AREA and FAIL - then *
  *                      the specified action in the set AREA or *
  *                      FAIL should be executed. The current    *
  *                      usage of the queues has not been used   *
  *                      to set the AREA till now- this caused   *
  *                      some sources to be iwaited even there   *
  *                      were no messages ( or not as much       *
  *                      messages as set in the AREA ) on the    *
  *                      queues.                                 *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The programs have been changed to set the AREA / FAIL based on
  the current usage of the queues - then the action in the set
  AREA / FAIL is taken.
  

Problem conclusion

• Apply the APAR. Restart the control region to get the changes
  activated.
