Estoy administrando un par de servidores para servicios básicos (NTP, DNS, etc.) y se me ocurrió que uno de los servidores parece mantener los 3 núcleos más recientes, en lugar de 2 en los otros:

Todos los servidores se mantienen de forma idéntica, no sé lo que podría haber hecho, debe ser un parámetro en alguna parte, ¡pero no puedo encontrarlo!
¡Por favor alimenta mi curiosidad! Gracias
