host a call a.php and open new ie call b.php
(this action make b.php wait for a.php success because it
use same sessionid not problem, when socket_timeout it make a.php end and b.php end)

Reproduce code:
---------------
a.php
<?php
session_start();
$url = "http://192.168.4.199/ar_master.php";

Thank you for taking the time to write to us, but this is not

host b call b.php not have any dependency b.php that call by host a, 
so i think it should not wait for host b.php success on on host a.
if i comment line shell_exec , host b can run b.php without any problem.
while shell_exec i test command shell_exec("dir");

i test this problem on freeBSD it does not any problem.
if i should read manual what chapter i read ? .
thank you very much.
