[Mediawiki-l] Purging 'Mediawiki messages' from memcached

[Carlos Jorge Andrade]

Hi,

Accidentaly it seems that the mediawiki messages (seen in  
Special:Allmessages) from a development server ended up on the live  
memcached servers. Now the live servers are displaying messages from  
the development database (memcached content).
I can confirme this because if I turn off the memcached option in  
LocalSettings all comes back to normal... the correct messages are  
displayed.

Using ?action=purge on the Special:Allmessages won't do nothing as  
also setting $wgCacheEpoch to a future date.

Is there a way to purge this content from the memchached servers, or  
ultimately all pages ? How can I reset this ?
I've search for something similar to maintenance/ 
deleteImageMemcached.php but didn't find anything.

Thanks.
