High CPU in 7600

[ehsan-khan]

In one of 7606 router we have 86% CPU usage.

Below is summary

CPU utilization for five seconds: 85%/83%; one minute: 85%; five minutes: 85%

PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process

63 11380 2841 4005 0.47% 0.13% 0.06% 1 SSH Process

191 6299376 24538237 256 0.15% 0.14% 0.19% 0 IP Input

227 58448 8455 6912 0.47% 0.08% 0.10% 2 SSH Process

291 13100592 3202421 4090 0.31% 0.17% 0.18% 0 HIDDEN VLAN Proc

My question there is no individual process is eating the cpu but it is showing 86%.

Any suggestion.

Thanks,

Ehsan

What the stats show is a processor very busy forwarding traffic. Which sup is the box? Any fabric, fabric cards and/or cards with DFCs? Any idea of the overall bandwidth being pushed? (W/o DFCs, even a sup720 or rsp720 is rated at about 15 or 30 Mpps.)
