as a general recommendation, i'd recommend that you run the 12.0S software
train (latest 12.0(x)S release) rather than a 12.1T release.
having said that, i don't believe that there are any major issues with WCCP
in 12.1(5)T.
given you see different characteristics between the NPE200 and NPE400, i'd
say that you may want to investigate your cache.
by the sounds of it, perhaps it has some kind of "overload bypass" facility
and isn't using the correct method to redirect unwanted traffic back to the
router. the use of an incorrect method results in a "traffic loop" with
unwanted traffic being re-intercepted and sent back to the cache - ad
infinitum --
i know of at least 2 cache vendors that "get this wrong".
cheers,
lincoln.
