Generación continua de errores de CalendarAgent en MacOS 10.12.4

Después de actualizar hoy a MacOS 10.12.4, comencé a recibir toneladas de posts de error / error en la console generada por el process CalendarAgent . Algunos de los errores se pegan a continuación:

 error: sql cached statement NSSQLiteStatement <0x7fae52e27ad0> on entity 'CalDAVError' with sql text 'SELECT t0.Z_ENT, t0.Z_PK, t0.Z_OPT, t0.ZCODE, t0.ZDOMAIN, t0.ZUSERINFO, t0.ZCHANGEREQUEST, t0.Z8_CHANGEREQUEST, t0.ZPRINCIPAL, t0.ZOPERATION, t0.ZPRINCIPAL1, t0.ZPUBLICATION, t0.ZSUBSCRIPTIONINFO FROM ZERROR t0 WHERE ( t0.ZPRINCIPAL IN (SELECT * FROM _Z_intarray0) AND t0.Z_ENT = ?)

La cantidad de errores generados en pocos minutos es más de 6000 !. ¿Cuál crees que podría ser el motivo? Si crees que necesito agregar más detalles, indícalo en los comentarios.
