Problem summary

• ****************************************************************
  * USERS AFFECTED: HATS Macro users                             *
  ****************************************************************
  * PROBLEM DESCRIPTION: Macro timeout error can potentially     *
  *                      lead to out of memory exceptions.       *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  In certain situations, when a macro failed to execute
  completely and timed out, HandleMacro objects were not being
  cleaned up properly.  As a result, over time an out of memory
  exception could occur on the application server.
  

Problem conclusion

• The HATS macro code was modified to clean up all HandleMacro
  objects when a macro fails to complete successfully.
