[c-nsp] Strange 6509 Error

[Paul Stewart]

Just a followup... We rebooted the unit overnight and the errors
continue.  This morning, the supervisors kicked over to the 2nd one for
no apparent reason... Have to presume that it is software related now
and possible IOS bug because the 2nd supervisor is complaining of the
same errors??

Thanks,
Paul

This is generated by the CEF consistency checker code (specifically,
checking the consistency of writes to the FIB SSRAM, which is the
"result" 
memory for your h/w FIB prefixes, meaning, containing the RPF VLAN, ADJ
pointer, & some other info).

This error is corrected by the software. Is this error happening
regularly or you just saw it once this morning? It is not anything to
worry about unless it happens regularly, in which case there could be a
software bug, or a problem in the FIB TCAM memory.
