APAR status

  • Closed as program error.

Error description

  • New XLXP parser causes a memory leak.
    
    When running internal tests with a request containing
    whitespace, a memory leak might be seen, and eventually can
    hit an OutOfMemoryError.
    

Local fix

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  WebSphere Application Server users who      *
    *                  have installed a V6.1 Feature Pack          *
    ****************************************************************
    * PROBLEM DESCRIPTION: The SAX parser may leave the            *
    *                      underlying InputStream open,            *
    *                      resulting in an OutOfMemoryError error  *
    ****************************************************************
    * RECOMMENDATION:  Install a fixpack that contains this APAR.  *
    ****************************************************************
    If a SOAP or XML message containing whitespace is passed to the
    SAX parser, and a subtree containing whitespace is skipped,
    the underlying InputStream may be left open, eventually
    resulting in an OutOfMemoryError.
    

Problem conclusion

  • The XLXP code was updated to remove the Out of memory condition.
    
    Note that this problem does not occur unless one of the
    feature packs for WebSphere Application Server version 6.1 has
    been installed, such as the Feature Pack for Web Services or
    the Feature Pack for EJB 3.0.
    
    The fix for this APAR is currently targeted for inclusion in
    fixpack 6.1.0.23.  Please refer to the Recommended Updates
