Patchman not using memcached

[kaiszy]

Hi,

i use patchman for ca. 80 Servers. I wonder because a nightly report run takes a very long time (about 6 hours). To speed up the process i add

# Enable memcached
CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': '127.0.0.1:11211',
    }
}

I reload apache2. But memcache will not be used:

[x@patchman userA]# memcached-tool 127.0.0.1:11211 display
  #  Item_Size  Max_age   Pages   Count   Full?  Evicted Evict_Time OOM

Have i to remove some cachefiles ?
