Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of WebSphere Intelligent          *
  *                  Management using the java On Demand         *
  *                  Router.                                     *
  ****************************************************************
  * PROBLEM DESCRIPTION: An Out Of Memory error can be seen on   *
  *                      the On Demand Router because            *
  *                      HttpRouteAction objects can             *
  *                      accumulate.                             *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  There is a code bug where default HttpRouteAction objects can
  accumulate because they are not freed. Over time this can
  cause exhaustion of the available heap and an Out Of Memory
  error for the On Demand Router.
  

Problem conclusion

• The area of code was corrected to release the default
  HttpRouteAction objects. However, another issue that is
  addressed in PI53566 supercedes this fix and corrects the
  issue for not only default HttpRouteActions but also
  non-default HttpRouteActions. PI53566 should be applied in
  place of this fix.
