Vbulletin 4.2.3 Patch Level 2 Memcache trouble

[Terje Andrè Børud]

I have installed and configured Memcached by following this thread: https://www.vbulletin.com/forum/blogs/dick/3936342-
When accessing the cache test file in a web browser i get this result: Server's version: 1.4.15 Data from the cache: stdClass Object ( [string_attribute] => 123 )


I have configured /includes/config.php as follows:

        // ****** DATASTORE CACHE CONFIGURATION *****

        // Here you can configure different methods for caching datastore items.

        // vB_Datastore_Filecache  - to use includes/datastore/datastore_cache.php

        // vB_Datastore_APC - to use APC

        // vB_Datastore_XCache - to use XCache

        // vB_Datastore_Memcached - to use a Memcache server, more configuration below

$config['Datastore']['class'] = 'vB_Datastore_Memcached';



        // ******** DATASTORE PREFIX ******

        // If you are using a PHP Caching system (APC, XCache, eAccelerator) with more

        // than one set of forums installed on your host, you *may* need to use a prefix

        // so that they do not try to use the same variable within the cache.

        // This works in a similar manner to the database table prefix.

$config['Datastore']['prefix'] = 'forum1_';

 // It is also necessary to specify the hostname or IP address and the port the server is listening on


$config['Datastore']['class'] = 'vB_Datastore_Memcached';

$i = 0;

// First Server

#$i++;
#$config['Misc']['memcacheserver'][$i]          = '127.0.0.1';
#$config['Misc']['memcacheport'][$i]            = 11211;
#$config['Misc']['memcachepersistent'][$i]      = true;
#$config['Misc']['memcacheweight'][$i]          = 1;
#$config['Misc']['memcachetimeout'][$i]         = 1;
#$config['Misc']['memcacheretry_interval'][$i] = 15; 

I am running centos minimal distro with apache 2 and Mysql-MariaDB.
nano /var/log/httpd/error_log gives me this error:

Memcache::connect(): Can't connect to :0, Failed to parse address "" (0) in /var/www/html/includes/class_datastore.php on line$

When running "top" command i get this for Memcache: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
5220 memcach+ 20 0 345120 2732 1176 S 0.0 0.0 0:00.27 memcached



Any help as to why memcached cannot connect will be greatly appreciated.
