El proceso softwareupdated parece estar ocupando demasiada memoria. A veces puede tomar hasta 400 MB de RAM. No puedo determinar qué es lo que está causando esto, así que he estado observando mi consola de cerca. He reducido un incidente a un período de 15 minutos, pero todavía no puedo ver lo que podría estar causando esto. Adjunto la salida de la consola a continuación. Normalmente el softwareupdated sólo ocupa 18 MB. Cuando llega a los 400 MB, no vuelve a bajar a menos que reinicie el ordenador. Es como si no pudiera liberar la memoria o algo así. Es muy frustrante ya que ralentiza mi ordenador considerablemente. También se me ha congelado el ordenador unas cuantas veces y he tenido que apagarlo manualmente. Parece que los problemas comenzaron con la actualización 10.10.2, pero esto puede ser una coincidencia.
edit: Aquí hay algunas capturas de pantalla actualizadas cuando el proceso está actuando. 
¿Alguien más ha experimentado esto? ¿Qué puedo hacer para solucionarlo?
