I suggest you turn on error_reporting(-1). Then you'll probably see
that the client can't connect, and hits a timeout. At least on my
German Windows box after 32 clients I get:
| Warning: stream_socket_client(): unable to connect to
| tcp://127.0.0.1:8080 (Es konnte keine Verbindung hergestellt werden, |
da der Zielcomputer die Verbindung verweigerte.)
[A connection couldn't be established, because the host refused the
connection.]
There seems to be a limit on allowed TCP connections; switching to UDP
works fine, though.
