This error is usually caused by an interruption in service to the repository database. 


Usually a restart of the TDoD service resolves this issue. 


If the TDoD service is not able to access the back-end database, the service (by default) will shut down, and this is by design. However, since TDoD is implemented as a Windows service, you can make a change to the service itself to restart the service if it goes down. Below is a link that talks about setting this up if needed-
