The CPU is being chewed up by fast switching, which doesn't show up in the output
except for five-second utilization. The percentage after the "/" shows
interrupt-level CPU usage.
I had a similar problem when we were migrating from Netware 4 to Netware 5. A couple
of different times we created routing loops and the processor usage on our 7513 went
berserk. After we cleared IPX routes, the problem went away.
