Здравствуйте, недавно поставили Cisco ASR1002-ESP10, трафик около 300Mb/s, на ней НАТ и BGP full-view, при этом CPU utilization for five seconds: 82%/1%, а иногда доходит до 97%. Процесс IOSD ipc task периодически то падает до 10-15%, то взлетает до 80-90%. Может кто-то знает причину такого поведения. Буду очень признателен:
Вот данные:
