Error when running scheduled task: ExpireOldTasks
System.InvalidOperationException: The maximum number of requests (10000) allowed for this session has been reached.
Raven limits the number of remote calls that a session is allowed to make as an early warning system. Sessions are expected to be short lived, and 
Raven provides facilities like Load(string[] keys) to load multiple documents at once and batch saves (call SaveChanges() only once).
You can increase the limit by setting DocumentConvention.MaxNumberOfRequestsPerSession or MaxNumberOfRequestsPerSession, but it is
advisable that you'll look into reducing the number of remote calls first, since that will speed up your application significantly and result in a 
more responsive application.
