¿Por qué se puede producir el error "There is already an open DataReader associated with this Command which must be closed first"?

Al momento de generar planilla, me muestra el siguiente error: System.Data.EntityCommandExecutionException: An error occurred while executing the command definition. See the inner exception for details. ---> System.InvalidOperationException: There is already an open DataReader associated with this Command which must be closed first.

¿Qué podrá estar causando este problema?

Encontré el problema: había modificado las cadenas de conexión del web.config y luego del último cambio, quedaron sin "MultipleActiveResultSets=True".

Le agregué eso a todas las cadenas de conexión y el error desapareció.
