Tengo un problema, tengo un Cisco 1841 con Cisco IOS 15 y tengo un comportamiento extraño. El uso de la CPU se muestra como 40%, pero no hay procesos que utilicen tanta potencia de la CPU.
Aquí hay un ejemplo:

No puedo encontrar qué está causando toda esta carga de CPU.
Me puedes ayudar ?
Aquí hay alguna información sobre el enrutador:
Cisco 1841 (revision 6.0) with 358400K/34816K bytes of memory.
System image file is "flash:c1841-adventerprisek9-mz.151-4.M1.bin"
El sistema acaba de actualizarse a IOS 15.4M1 desde IOS 13.
Gracias.
