[c-nsp] Sup720 Errors - Revisited

Thanks Ibrahim - I tend to agree (as much as I don't like too).  The strange
thing is that the 6500 where this same error occurred is 100 miles away in a
different data center, but we've only really seen it occur there once...


I was *really* hoping someone had come across these errors and found it to
be in software somewhere but it doesn't look like my luck is going to get
that good ;)


Take care,

Hi Paul


I think it is a phsyical problem with this chases , may be due to the
position or electrical conditions causes some sort of biasing for memory
ASIC and leads to this reload loop


you can start check chaises postition , electrical isolation , grounding and
supply and tenperature


and if it didn't work , might be persistent problem with backplane 



best regards

Hi folks.

I posted about this before and was told it was either bad memory or bad sup
cards.. Have a pair of 7606's with sup720-3bxl . these errors occur on one
system and not the other.  To top it off, we got these same errors showing
up a couple of times now on 6509 with sup2/msfc2 recently..

May  9 07:16:21: %SYSTEM_CONTROLLER-SP-STDBY-3-ERROR: Error condition

Controller is getting reset so frequently

Both 7606 chassis are running 12.2(33)SRA7 and this also occurred when they
were running SXF train.   We have many 6500's and only one of them so far
has exhibited the same errors and it is running 12.2(18)SXF16

Just looking for thoughts. we swapped spare supervisors between the 7600
showing issues and the one that doesn't log any errors, kicked it over and
still see these issues.. Bad chassis??

Are these errors critical in nature or more just informative?

Thanks for your time,
