Rui:

The correct thing to do is to complain to the vendor or author of the
daemon.  They should be using setsockopt with the SO_REUSEADDR argument
for all sockets they bind to in their code.  This doesn't answer you
original question, exactly, but I do forget whether you only have
to wait a few minutes before you can reuse the port+address or
you have to reboot the machine.  Even so, the application is
broken.
