Hi Expert,

%C4K_RKNOVA-2-EDACSOFTERROR: Excessive number of correctable CPU L2 cache soft errors

I don't found in any docs and error decode tool.

Anyone have ever got this error messages? is it serious?

Thanks in advance.

Hi Rojer,

This logs indicates that there is ECC error on switch and this error is a sign of failing memory on the CPU.

The ECC error indicates a single byte parity error occurred which the Error Correcting Code on the switch was able to recover from. Parity errors are usually one-time transient events.

Do you see this error continuously on the switch? please share the below logs, to understand this behavior

#show version

#show module

#show log

Regards,

Aru

Hi Aru,

Thanks for reply. No more error re-happening. It look like to be one time error.

Hi Rojer,

Thanks for your kind response. If you start to see this error message continuously, that indicates the HW problem, you may need to replace the supervisor.

Its good to see that the error not re-occuring again, so we can conclude this is kind of transient behavior.

Regards,

Aru
