That fixed the problem. So, is this the right solution? Should configure always assume --disable-threads when it sees --with-mpm=prefork? Given that this problem does not show up with low numbers of children, I am kind of wondering if disabling threads is just covering up some problem that should not affect prefork. Thoughts? -adam
