fedora-users: localhost udp bind: address in use

localhost udp bind: address in use

I have some complex multi-thread C++ code in which I do
some internal signaling with udp sockets:
snd: 127.0.0.1:6501
rcv: 127.0.0.1:6502

On my new F15_64 box, I usually get:
errno=98=Address already in use
in response to the bind command when I bring up the snd
socket (which is first up) even when I just come up from
power off.

Rarely, it works. I have no idea why.

If I ignore the 98 error, I get a write error on the socket.

Even when it fails,
netstat -uap
shows the socket, which is not a surprise, and it
is not there when the program is not up.

Now on my old CentOS 5_32 box, the same code
(but, of course, compiled for 32) works with no
problem. I can start and stop it rapidly with no
problem.

Thanks for your suggestions.
Mike.
