rugwuk has asked for the wisdom of the Perl Monks concerning the following question:

Hi all,

I've searched around and found some useful references for using HTTP::Daemon, and have got a simple web server up and running very easily using this module and the examples from Randall etc. I fork a child to do some work from the main daemon and that works just fine and dandy.

My problem is that sometimes (Solaris 2.8 BTW), when i kill my daemon during testing and start it again on the same PORT i get "Address already in use", and i can't seem to see why, as the process i was running is clearly dead.

Now its doesn't always fail, just sometimes. I scoped out netstat -a on my port and found a WAIT_TIME entry for my port number, but wasn't sure if this was related or not? eventually the PORT does become free, but i haven't managed to track down exactly when yet.

I know this isn't strictly perl, but it might be, and am trying to rule it out. Is there a particular way i should kill the process, currently just Ctrl C, to make sure that any hanging resources are released?

Thx in advance and Rgds Richard

      Note that use of Reuse have been deprecated in latest Perls (5.6.1 ???). From perldoc IO::Socket::INET (base class of HTTP::Daemon): 
          In addition to the key-value pairs accepted by
    IO::Socket, "IO::Socket::INET" provides.

        ....
        ....
        ReuseAddr   Set SO_REUSEADDR before binding
        Reuse       Set SO_REUSEADDR before binding
                    (deprecated, prefer ReuseAddr)
        ReusePort   Set SO_REUSEPORT before binding
