[c-nsp] 3750 stack with high CPU from IP Input process.

[Bill]

    I ended up rebooting the switch stack last night and guess what? The CPU
went back to 5%. I've sent this to Cisco asking them if there is a bug in
the IOS.

The next time it happens, post the results of a "sh proc cpu" & maybe
someone can figure out what's causing the cpu busy.  Or at least say it's
caused by snmp, spanning tree, or whatever.

Other good stuff to look at is the results from
sh ip traffic
  need to do it twice - the deltas are what's interesting
sh int
  5 minute in.out rate is interesting, deltas for errors etc. are
interesting
