Corinna,

We just tried the latest snap shot and the example fails.

I want to confirm that you ran the sample properly.

Did you do a "telnet hostname 5210" to allow the program to
continue the the second fork, which fails?

You will get the command prompt back because the sample
"daemonizes", but you need to telnet to it to allow
the daemon to continue.
