RE: [nsp] MSFC CPU Utilization Pegged at 99%....but a sh proc cpu does not reveal anything past 1%

Is this spent at the Interrupt level? Recall that the process utilization
adds up to the difference between total 5 second CPU utilization, and time
spent at the interrupt level switching packets. It is likely that MLS is
hosed, or CEF is busted/off on the MSFC2, and the CPU is switching all the
packets in the fast or process path. Since IP_Input appears idle, then it
is likely fast switching. Can you snip over a show proc cpu?

Have a 6509 with 2 MSFC's. The MSFC's are running 12.1(2)E. Just had one
of the MSFC's spike to 99%. A sh proc cpu reveals that total utlization
should add up to about 5%. A reload of the module causes the exact same
thing. A no changes have been made. Anybody seen this before. Also, the
other MSFC and Switch Utilization are both showing about 3-5%, which is
normal.

Thank You,
Patrick Greene
