An error occurred: ['memcachedserver:11211']

    cache = cls.loadFromSection(config, "cache", Cache)
  File "/var/www/cgi-bin/tilecache/TileCache/Service.py", line 75, in _loadFromSection
    return section_object(**objargs)
  File "/var/www/cgi-bin/tilecache/TileCache/Caches/Memcached.py", line 11, in __init__
