I'd just like to iterate that the WORKER and the threaded MPM do work. and make it worth considering apache 2.0 for production environments, where you are seeing your memory requirements get pushed to the limits, we have seen 1.3's servers happily use 1-4G of memory on our production boxes. under the same loads we see ~500M usage with 2.0 --Ian > > Pier (working his ass off on a deadline!) >
