Well, switching it off makes it slower, so that's not really solving the 
problem.

It only happens once every 2 days...

For me it would be ok to just disable/clear the cache in the situation 
when this error would happen.

So at least i need some hint from someone who knows the code.

Here again the error message:

The ext_localconf.php cache part from extbase looks like this:
// use own cache tables
// Reflection cache:
$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['cache_extbase_reflection'] 
= array(
         'frontend' => 't3lib_cache_frontend_VariableFrontend',
         'backend' => 't3lib_cache_backend_DbBackend',
         'options' => array(
                 'cacheTable' => 'tx_extbase_cache_reflection',
                 'tagsTable' => 'tx_extbase_cache_reflection_tags',
         ),
);
// Object container cache:
$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['cache_extbase_object'] 
= array(
         'frontend' => 't3lib_cache_frontend_VariableFrontend',
         'backend' => 't3lib_cache_backend_DbBackend',
         'options' => array(
                 'cacheTable' => 'tx_extbase_cache_object',
                 'tagsTable' => 'tx_extbase_cache_object_tags',
         ),
);

Cheers,
