While I can't supply any answer, the thing that is eating up the CPU is rpd, the main routing daemon. It is reading the kernel queue if it is in the kqread state. To see the route processor using 44% of the CPU is rather high. Even on our core routers I generally only see 3-5% CPU use by rpd. It runs much higher at time when there is routing instability. -- R.
