[TYPO3-dev] How to use Xcache for backend

[Florian]

Hi,

I'm trying to use Xcache for caching Typo3 backend.
I have the following configuration in my LocalConfiguration.php

     'SYS' => array(
         'caching' => array(
             'cacheConfigurations' => array(
                 'cache_hash' => array(
                     'backend' => 
'TYPO3\\CMS\\Core\\Cache\\Backend\\XcacheBackend',
                     'frontend' => 
'TYPO3\\CMS\\Core\\Cache\\Frontend\\VariableFrontend',
                     'options' => array(
                         'servers' => array(
                             'tcp://127.0.0.1:11211',
                         ),
                     ),
                 ),
                 'cache_pages' => array(
                     'backend' => 
'TYPO3\\CMS\\Core\\Cache\\Backend\\XcacheBackend',
                     'frontend' => 
'TYPO3\\CMS\\Core\\Cache\\Frontend\\VariableFrontend',
                     'options' => array(
                         'servers' => array(
                             'tcp://127.0.0.1:11211',
                         ),
                     ),
                 ),
                 'cache_pagesection' => array(
                     'backend' => 
'TYPO3\\CMS\\Core\\Cache\\Backend\\XcacheBackend',
                     'frontend' => 
'TYPO3\\CMS\\Core\\Cache\\Frontend\\VariableFrontend',
                     'options' => array(
                         'servers' => array(
                             'tcp://127.0.0.1:11211',
                         ),
                     ),
                 ),
             ),
         ),
         'useCachingFramework' => '1',
     ),

Unfortunately when I'm trying to display the site I have this message : 
Oops, an error occurred!

Best regards,
