Address and port are already in use

Please help!

I have daemon listening on port 80. After working for few days if I
stop it I cannot start it again - it cannot open socket for listening
with error something like "Address and port are already in use". I
checked that process is not running and netstat/lsof are saying that
there noone is listening on port 80.
The only was for me to start service again is restarting network
service (service network restart) - after this operation my daemon
starts as it suposed to.

Thanks in advance.

Evidently is not stopped completely, maybe you need to kill him.

There are no process in the system with that name, and with netstat I
see no sockets with that port.

Thanks

Well, from what you said it seems a problem in the socket being in use,
try to ask the developer of that software if they know of such bug.

App finished gracefully, it closes all sockets. And then on start it
just cannot open port.

Thanks

You may try

#v+
int x, err;
err = setsockopt(socket, SOL_SOCKET, SO_REUSEADDR, &x, sizeof(x));
#v-

before bind(). Netcat also sets SO_REUSEPORT when it's available.

Hope it helps.
