SimpleMembership looses track of connection after timeout

Hi,

After timeout, it seems that SimpleMembership looses track of the connection string. I spins into an error, citing problems on network connection, and saying that it was unable to create database. The only connection string I have in the application, is to a database on Azure. Actually, it puzzles me as to why it doesn't lead to a redirect to the login instead. I have tried for hours to debug this, but I cannot find the right place to step in, so I don't know where exactly this happens. 

It's and MVC 4 web application.

Any ideas?

Thanks,

Anders
