The first question is whether you mean real "zombies" (as indicated by ps)
or a bunch more process than you expected ("process leak"). I've seen the
latter a number of times and it generally indicates failure to properly
close connections in your application. I find the same techniques used for
debuging file descriptor leaks work for finding these problems.
