Re: c6509 High CPU CEF SCANNER

To be clear, my CPU has been pegged all day.  I have had a few emails from a friend who hints at

lots of young routes. Not sure hot to tell about that.

To follow up, the issue went away. I am rather disappointed as i need to understand

what happened. If it happens again i will post.. If anyone has experience CEFSCANNER 90% for a long period

and fixed please reply.

Thanks

Chris
