Hi Arul,

A classic configuration is a terminology for IOS configuration files and consists of a stream containing the system?s configuration using the IOS command language schema.

CRS does not really use classic config space and classic config space are basically no use to CRS. In most corruption cases, the issue were recovered by auto-recovery in the NVRAM PI code asin your case.

I see the NVRAM has recovered from it and the logs should not be seen again.
