Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM HTTP Server users of the optional       *
    *                  mod_dav module on a Microsoft Windows       *
    *                  server                                      *
    ****************************************************************
    * PROBLEM DESCRIPTION: The gathering of extra unneeded         *
    *                      directory info was affecting DAV        *
    *                      performance on Windows servers.         *
    ****************************************************************
    * RECOMMENDATION:  Apply this fix if using mod_dav on a        *
    *                  Windows IHS server.                         *
    ****************************************************************
    The retrieval of filesystem info about directory entries when
    processing a DAV (Distributed Authoring and Versioning)
    request was excessive.
    The resulting slow request issue has been resolved by
    minimizing this filesystem info retrieval.
    

Problem conclusion

  • A mod_dav performance issue was resolved by gathering only the
    needed filesystem info.
    
    This fix is targeted for IBM HTTP Server fix packs:
     - 7.0.0.31
     - 8.0.0.7
     - 8.5.5.1
