[c-nsp] 6509 IOS Question

[Rodney Dunn]

check heaps runs every 60 seconds in the background.

You have enough traffic being switched by the MSFC at
interrupt level causing the CPU there (if 'sh align' is
clean).

Check 'sh int stat' and see if that gives you a starting
point on what interfaces to focus on. Clear the counters and
watch it for a couple minutes.
