Offtopic : I need a little help with a C program

[Stefan Sonnenberg-Carstens <ssc@coolspot.de>]

I wrote a little server which should become the base
of a small specialized proxy.
I can compile, and it runs.
But if I do on a shell something like

while true ; do curl http://localhost:8271 ; done

it creates zombie processes after a while.
I can't see why.

Any ideas ?

Thx in advance.

P.S.:
I know my C code looks not so nice ...
... I make it look better when I fully understand what's going wrong here
