Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server web        *
    *                  server plugin users                         *
    ****************************************************************
    * PROBLEM DESCRIPTION: The WebSphere plugin can crash when     *
    *                      connection errors occur to the          *
    *                      application servers.                    *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When connection failures occur to the application server,
    plugin attempts to report as much information as possible
    about the failure. In some cases, this reporting will cause a
    crash because connection-specific memory is referenced after
    it has been released and is no longer valid.
    Call stack of the crash will have the following functions at
    the top of the stack:
    #0 detailedLog
    #1 websphereExecute
    #2 websphereWriteRequestReadResponse
    

Problem conclusion

  • Code has been corrected to prevent accessing released memory
    in the detailed error reporting.
    
    The fix for this APAR is targeted for inclusion in fix pack
    8.5.5.20 and 9.0.5.8. For more information, see 'Recommended
    Updates for WebSphere Application Server':
