Wow. Nice thread, You'll go far in life with an attitude like that. I
assume you are not being paid for this support. If you were my employee
I would fire you on the spot.

Stil a FAIL:

Warning: fsockopen(): php_network_getaddresses: getaddrinfo failed: Name
or service not known

Then we go back to the first post and there is a 2 line example of the 
problem.

Reproduce code:
---------------
<?php
$socket = fsockopen("somehost", 631313, $errno, $errstr);
stream_set_blocking($socket, 0); // non blocking

this is enough to trigger the problem.
I hope this is short enough.

Strike 3. As long as you can not provide a short reproducing script
(like described in my first comment to this report) the bug is most
likely something you did wrong.

Here is a complete undressed file which only has the problem.

I asked for small, complete script NOT for a framework.
