If this code is added to a load balanced server, you are unable to perform session based actions such as logging in. An initial entry into the sessions document, and the "expires" value appears to update on page refreshes, but it simply will not allow user actions such as logging in.

If the code is tested on individual servers (bi-passing the load balancer), it works perfectly.

Via a comment on original blog post:
"We've found through load testing this code has the following problem: it calls the "disconnect" method on the server object in several places. This may cause the Mongo driver to run out of connections and fail to connect to the server.

It turns out that the disconnect should not usually be invoked; it's better to let the driver handle the connection pooling internally.

See for example this blog post: http://craiggwilson.wordpress.com/2012/09/23/disconnecting-with-the-mongodb-driver/"

Bottom line, is that there is no need to call Disconnect() on a MongoServer instance. The API docs for the C# (http://api.mongodb.org/csharp/1.6/html/71b2d2c6-4c2d-ec27-b465-071dee0dd2f6.htm) state: "Disconnects from the server. Normally there is no need to call this method so you should be sure to have a good reason to call it." - I have no good reason to call it, so will remove those calls.
