Memcached configuration error

[sed]

I'm really struggling with an error I receive when unit testing with
Memcached configure for the second level cache

The stack output shows
--NullReferenceException
at Memcached.ClientLibrary.SockIOPool.Initialize()
at NHibernate.Caches.MemCache.MemCacheProvider.Start(IDictionary`2
properties)
at NHibernate.Impl.SessionFactoryImpl..ctor(Configuration cfg,
IMapping mapping, Settings settings, EventListeners listeners)
at NHibernate.Cfg.Configuration.BuildSessionFactory()

(23,0): at Mytrade.Core.Persistence.NHibernateSessionManager..ctor()
C:\MyTrade\Mytrade.Core\Persistence\NHibernateSessionManager.cs
(16,0): at Mytrade.Core.Persistence.NHibernateSessionManager..cctor()

Heres my entire configuration file. I don't see what can be wrong

Does anyone have any ideas?

Nope. It still isn't working but if I stick the Hashtable provider in
there it works.

No clues anyone as to what I could have misconfigured?

I've moved everything to the app.config and no longer get the
NullReferenceException, yet it still does not use the Memcache server
and instead hits the database. Switching back to the Hashtable
provider does work.
