Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server            *
    *                  traditional version 9.0 users of JSP and    *
    *                  WebSphere Liberty users of JSP 2.3          *
    ****************************************************************
    * PROBLEM DESCRIPTION: A java.lang.OutOfMemoryError could be   *
    *                      thrown when JavaServer Pages files are  *
    *                      requested.                              *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    If a web module contains JSP files, a java.lang.OutOfMemoryError
    could be thrown if the JSP pages are requested a high number of
    times while the server is running. The error could happen with a
    single JSP page if it's requested enough times that the
    allocated memory is insufficient to store the internal metadata
    of this JSP page. Note that the size of the JSP itself is
    irrelevant for this OutOfMemoryError.
    

Problem conclusion

  • The JSP engine was modified to create a single metadata object
    per JSP page instead of creating a metadata object on each JSP
    page request.
    
    The fix for this APAR is currently targeted for inclusion in fix
    packs 9.0.0.8 and 17.0.0.4.  Please refer to the Recommended
