Read the PHP warning in the documentation at
http://php.net/manual/en/function.session-set-save-handler.php.
Although the sqlsrv connection resource does not appear to be an object, it is destroyed at the object level. The solution is to put your session handlers in a class, and in the destructor, call 'session_write_close();'.

Here's my version:

function SetSessionHandler()
{
static $s_sess;
$s_sess = new CSession();
session_set_save_handler(
array($s_sess, 'sess_open'),
array($s_sess, 'sess_close'),
array($s_sess, 'sess_read'),
array($s_sess, 'sess_write'),
array($s_sess, 'sess_destroy'),
array($s_sess, 'sess_gc'));
}

The class:

class CSession
{
public $conn;

function __destruct()
{
session_write_close(); // IMPORTANT!
}

function sess_open($save_path, $session_name)
{
this->conn = sqlsrv_connect(...);
// ....
}

function sess_close()
{
}
function sess_read()
{
}
/// add all the session functions.
}
