Hmm. That's pretty odd --- the warning indicates that
StreamServerPort() failed to open a local socket, but all of the
expected failure paths will log an additional message saying why
it couldn't open the socket.
The only code path I see offhand in which no message would be logged
is if the ListenSocket[] array is already full. Is it possible that
you have 10 or more IP addresses that "localhost" would bind to?
