Sometimes following error occurs, when we try to executing a procedure on 
database like this:  db.Database.ExecuteSqlCommand("execute procedure...")

An error was reported while committing a database transaction but it could not 
be determined whether the transaction succeeded or failed on the database 
server. See the inner exception and 
http://go.microsoft.com/fwlink/?LinkId=313468 for more information.

It happens every few days, that we get NullReferenceException in our 
web-service. This happens on select and also on update (save changes). We can 
now only "fix" it, when we restart the web-service (pool). 

Callstack - Select: It happens on ToList(), First(), FirstOrDefault()
