[nsp] 7200 Platform - Buffer Failures

We are seeing some buffer failures across the platform on the 7200
series routers in our network.  This comprises 7204/7206/7223/7246.
We're running 12.1(13)EC4 on the 7223/7246 platform and 12.2(15)T5 on
the 7204/7206 platforms.  Funnily enough on the 7200 routers that we are
running service provider code, we do not see the failures. I understand
that buffers can, at times, be busy, etc.  I'm just not sure if this is
normal to see so many simultaneous failures.

Has anyone else seen any problems like this?

Here's some output from the 'sh buf fail' command on a 7223:

#sh buf fail
