[PHP] Unexplained Socket Error

[David Buerer]

Anyone know why I might get this error?

I was working on development of a socket server several weeks ago and it was
working fine.  When I returned to it this morning, I am getting this error:

Listening on port 1482 (sucess message from socket_create)
Warning: socket_bind() unable to lookup host [1001]: Recursion too deep,
stack overflowed. in test_server.php on line 31
AIEE -- Couldn't bind! (failure message from socket_bind)

Line 31 says : 
if (!socket_bind($listenfd, "172.25.190.4", $PORT))
{
    socket_close($listenfd);
    die("AIEE -- Couldn't bind!\n");
}
