The error message is correct. When there are still connections
attached to the bound port and the program listening on the port
goes away, the kernel does not allow reattaching to the port until
a timeout - which I think should be around 2 minutes.
You can tell the kernel to blow it off and allow reattachments with
the SO_REUSEADDR socket opt.
int on = 1;
setsockopt(lfd, SOL_SOCKET, SO_REUSEADDR, (void *)&on, sizeof(on));
listen(lfd, ... );
