Re: How to Troubleshoot the High CPU Utilization in Cisco IPS 42

We have a 4260 going high CPU and causing up 2 seconds of delay. We also are unable to find cause and have to go into bypass mode. We see this when transfer traffic is exceeding about 50Mbit/sec through the link. So far a terrible process getting Cico to help find what causing the high CPU. Any help in determining if a signature of getting abused or some other cause would really help us.
