    *                      backtraces.                             *

    ****************************************************************
    Enhance mod_whatkilledus to print backtraces.
    Due to an error in early full installs of IHS 855 and 9.0, the
    default configuration mistakenly omits mod_backtrace but
    includes mod_whatkilledus.
    By adding mod_backtrace logic to mod_whatkilledus, backtraces
    will be available in the error_log more frequently without
    requiring waiting for a subsequent crash.
    

Problem conclusion

  • mod_whatkilledus will now print backtraces.
    
    The fix for this APAR is targeted for inclusion in IBM HTTP Serv
    fix packs 8.5.5.21 and 9.0.5.9. For more information, see
