I wondering if anybody else has seen the symptoms I've seen below:
The symptoms we see are intermittent chronic slowdowns and connectivity
failures on the LAN, which seem to start and stop for no apparent reason.
Logging on to the switch to view errors as they happen and looking at
logging buffers shows MAC addresses flapping between seemingly random ports,
which may or may not have devices connected to them. Shutting down these
ports gets rid of the errors coming up on the screen, however after a time
the errors move to other ports and the slowdowns/connectivity failures
continue. On both occasions I have seen this a reboot was atempted,
initially with no apparent difference, however on both occasions a
subsequent reboot showed the supervisor engine as being faulty and failing
at the Power on self test.
In both cases we already had a support engineer on site looking at the
switch at the time the supervisor engine failed (i.e. the switches were
under maintenance and we had logged a call).

What software version are you running on the CAT4k's?. Make sure you are running 5.5(15) if you are in 5.x train or 6.3(7) in the 6.x train. The newer CAT OS has lot of bug fixes and does a better job in doing isolating bad/flaky hardware. Also look at the bugs discussed in the following field notice

I believe it was either 5.5(4) or 6.1(2).
I'll probably investigate upgrading the software in all our 4k's, since we probably have 100+ in our WAN.

my 4006 mod 1 sup II shows this
Hw : 3.2
Gsp: 6.1(3.0)
Nmp: 6.1(3)
Should I upgrade my firmware?
