1712 High Processor Utilization

[m-sherman]

Hello,

I am running a 1712 12.4(25d) with NAT, VPN and FW/IDS.  I have a broadband ethernet connection at 20mb.  As I run some traffic through it, the processor jumps up to near 100% and throughput comes to a screeching halt.  IP CEF is turned on and makes no difference when it is turned off or on.

Anyone have any ideas?

Hello,

What does show proc cpu sort show? Any interfaces which have increase in traffic (show int)?

Nik,

There are 3 processes that are running individually running less than 1% each.  My "WAN" interface pointing toward the ISP runs about 3MB/200 packets/sec.  I've disabled IDS on that interface with no decrease in CPU utilization...

Can you please provide output of  "show proc cpu sort".
