In addition to missing your patch, it looks like SelectServer.pm hasn't been touched at all since 0.28. As such, since SelectServer.pm implements it's own data(), it is therefor missing support for the data hook and for AUTH. It is also more lenient about barelf than is SMTP.pm. > > How does the memory footprint compare for forkserver vs selectserver, > > assuming linux kernel 2.6?

That's what I thought, but I'm using enough memory to suspect that perl makes a special effort to scribble all over the pages it allocated before forking. Do you by any chance know of a way to tell how much data is being shared via cow? Brian
