Hm, that's very curious indeed that only this 4006 is experiencing the
CPU spikes and the other 4006 are playing nicely. ^_^ Before I start
thinking you should turn on hardware or CPU debugging, try seeing if a
newer IOS rev might help. Is it possible that this particular 4006 is
getting hit more than the other 4006 you have?
I see that you're running an early deployment 12.1(13)EW2 and it seems
there's no newer revision of EW since July of last year for (13). But
I found this on Cisco's site about high utilization and they recommend
using 12.1(20)EW or newer. Here's the quote from the article (linked
below):
"For Catalyst 4500/4000 Cisco IOS Software-based Supervisor Engines,
consider upgrading to Cisco IOS Software Release 12.1(20)EW or later,
which introduces an enhancement of the internal management packet
handling mechanism by the CPU."

I deal with 5300s mainly at my operation but there were many problems
solved once I migrated from a very old IOS 12.2.5 (3 years old!) to a
recent one (12.2.17a) and it solved 95% of all strange anomalies, bus
error reboots, CPU utilization, and memory leaks. When I finally tried
out 12.3, all of our strange problems went away. I finally settled on
12.3.5b, which is running like a champ, and don't think I'll change it
for another year. I think your best bet is to go with the
recommendation from Cisco to do 12.1(20)EW or newer, which is
12.1(20)EW1. I think the worst case scenario is that a new IOS will
determine if it is hardware failure or software failure. Good luck!
