I´m getting an error in one of my hosted´s applications that execute a custom workflow made in Workflow Fundation.

When starts a new session de log show the information
10/26/2012 9:19:52 PM: CCA: Sessions.AddSession: Adding new session: 'Session Name'
10/26/2012 9:19:52 PM: CCA: Sessions.SetActiveSession: Switching to session: 'Session Name'
