zombie question

[jianchen at my-deja.com]

Hi,all!

I am programming a smtp server in python. It works fine now except that
it will left some zombie processes when the clients disconnect from my
server.

I have tried some methods from W.R.Stevens's famous work Unix Network
Programming such as catch the SIGCHLD signal in the daemon process. But
strangly when the child process exit, no signal send! Even when I
explicitly use kill to send SIGCHLD signal to the parent process, the
signal function seems not get called! ;(

Is there something I missed?

tia.
