Memcache not being cleared on cache flush When clearing the cache, either through /admin_menu/flush-cache or drush cc all, the cache isn't cleared, without errors. I've tried doing it directly through telnet, on memcache, getting "OK" as result, but old pages are still being presented to users.

I am using the Memcache module 1.10; in the settings.php file, I added the following.

$conf['cache_inc'] ='sites/all/modules/memcache/memcache.inc';
$conf['memcache_servers'] = array(
  '127.0.0.1:11211' =&gt; 'sessions',
  '127.0.0.1:11212' =&gt; 'cache',
);
$conf['memcache_bins'] = array(
  'cache' =&gt; 'cache',
  'cache_form' =&gt; 'database',
);


Although the session bin is configured, it's not in use. I also have http://livebookmark.net/journal/2008/05/21/memcachephp-stats-like-apcphp/ set up, tried using the "Flush this server" option, and get OK as result.
Turns out it wasn't a memcache problem but a LESS preprocessor issue.
