Re: 4006 cpu utilisation is more than 70%

Hi

Was this before or after the Security Notice - SQL Worm.

Please check the below and see if it explains why you are having high cpu.

Thanks

Posted: January 25, 2003

Summary: Cisco customers are currently experiencing attacks

due to a new worm that has hit the Internet. The signature

of this worm appears to be high volumes of UDP traffic to port

1434. Affected customers have been experiencing high volumes

of traffic from both internal and external systems.

Symptoms on Cisco devices include, but are not limited to high

CPU and traffic drops on the input interfaces.

Re: 4006 cpu utilisation is more than 70%

This is from last couple of days around a 15 days, I did a port scan on the lan and found that udp port 1433 or 1434 is not used on the lan.

What else can be reasons for this to happen?

Re: 4006 cpu utilisation is more than 70%

Do you see Xmit-Err counter increment on unconnected ports? I suggest that you upgrade to latest 5.5(x) which is 5.5(18) and see if you still have the issue. Also the following page should help

Re: 4006 cpu utilisation is more than 70%

There is no increment in xmit-err on unconnected ports, also i have gone through the document, I found that there are more number or xmit broadcast's, multicast's and unicast's. but this is not being reflected in process cpu, will the broadcast's effect the cpu utilisation? if yes what are the ways by which broadcasts, multicasts and unicasts can be reduced?
