i can't
i've inserted this config's to my config.php :
$config['Datastore']['class'] = 'vB_Datastore_Memcached';
$config['Misc']['memcacheserver'] = '127.0.0.3';
$config['Misc']['memcacheport'] = '11211';
$i = 0;

$i++;
$config['Misc']['memcacheserver'][$i] = '127.0.0.3';
$config['Misc']['memcacheport'][$i] = 11211;
$config['Misc']['memcachepersistent'][$i] = true;
$config['Misc']['memcacheweight'][$i] = 1;
$config['Misc']['memcachetimeout'][$i] = 1;
$config['Misc']['memcacheretry_interval'][$i] = 15;

also results of typing this command in ssh :
[root@xxxxxx /]# /usr/local/bin/memcached -u nobody -d -m 64 -l 127.0.0.3 -p 11211
