Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server web        *
    *                  server plugin users                         *
    ****************************************************************
    * PROBLEM DESCRIPTION: The web server may crash when the       *
    *                      plug-in configuration is dynamically    *
    *                      reloaded.                               *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The last line in the plugin trace file from the crashing
    process prior to the crash will be an entry from
    webSphereEndRequest if running at plugin trace level DEBUG or
    TRACE. The last stack entry on the crash data will also
    indicate websphereEndRequest.
    

Problem conclusion

  • The code was referencing data from the old configuration file
    when the request finished processing. This reference can cause
    a crash if memory tooling is configured to monitor for memory
    overwrites or misuse.
    
    The fix for this APAR is targeted for inclusion in fix pack
    8.5.5.18 and 9.5.0.5. For more information, see 'Recommended
