Re: High interrupt cpu usage on 7206...

Andrew,
thanks. As most of the CPU is being chewed at interrupt time, there is
no process in the process list that has any significant portion of it.

That document (and many others) redirect to

http://www.cisco.com/c/en/us/support/docs/routers/7500-series-routers/41120-highcpu-interrupts.html

Which I'm starting to memorize already :-/
