Description

just run a couple of nodes, freeze one of the downstreams with a "kill -STOP"
while running this simple piece of code:
{code}
<?php

ini_set('display_errors', 1);
error_reporting(-1);

if (! extension_loaded('memcached')) {
    dl('memcached.so');
}
$sessionId = $argc > 1 ? $argv[1] : md5(mt_rand());

ini_set('session.save_handler', 'memcached');
ini_set('session.save_path', 'localhost:11211'); // host:port

session_id($sessionId);
session_start();

printf("Session %s: %s\n", $sessionId, var_export($_SESSION, true));

$_SESSION['timestamp'] = time();
{code}

it will randomly fail
