Introduction
In order for the master controller (and Forecasting Shell Server) to run properly several maintenance workflows must be scheduled. These workflows make sure the database does not overflow (they run the rolling barrel) and that configuration marked to be removed using the Configuration Manager actually gets deleted. In addition, each FSS must also run a rolling barrel task, usually once a day. This task runs the rolling barrel on the FSS and deletes configuration marked for deletion.
