[c-nsp] C6500 C6KERRDETECT-SP-2-FIFOCRITLEVEL

[Sukumar Subburayan (sukumars)]

There is actually no need to swap chassis. 

This error message indicates that the SP-CPU inband port (the internal 1
Gig connection) FIFO 
pointers were not moving for certain amount of time possibly indicating
something wrong between
the CPU and it's inband connection. All this is internal to the
Supervisor. 

If the errors are persistant, the active sup might eventually reset or
switchover (in case there is 
standby). As part of the upgrade process, the transient condition
probably got cleared.

I too had the suggestion of reseating the module on the cisco forum.  I
agree with you in that the machine still seems to be processing packets
fine and no evidence of problems.

I will give the newer IOS a try and see if that helps as it did for you.

Thanks for your suggestion.

Regards,
John
