Hello,

looking at the device's CPU processes I have noticed that more tha 95% of utilization is "idle".

On the Cisco IPS Manager Express I can see under Sensor Information: Analisys Engine Status: Reconfiguring the Engine and user activity: LoadConfigtrojan.udp

Can anyone help?

Thanks!

Hello Carlo,

What version of IPS code are you running? This issue was seen in early 2010 when running early versions of 6.2 and 7.0. It is usually accompanied by a core.txt, which can be seen in the output of a "show tech."

If you would like to further investigate the issue, please open a TAC case and attach a "show tech." Alternatively, an upgrade to the latest code in your train should resolve the issue.

Thank you,
