Hi Kemin, I do not think that your taint problems are related to setgid. My experience with taint has taught me not to trust the error output. In this case, you are using ModPerl::Registry which means that your script could be the one which is supplying tainted data. Are you sure that you are untainting all input to your script? If you still can't find the problem, I suggest that you run the server in debugging mode[1].
