These messages indicate that there was a parity error in the Netflow 
statistics SSRAM.

You can do a 'remote command switch show earl statistics' and check to see 
if 'NS_ERR_CNT' is incrementing rapidly.

The effect is that, for the specific entry in the SSRAM which has the 
parity error, you will not be able to get Netflow statistics, as we don't 
create netflow entry for flow hitting that entry. However, there should 
not be any issue with data forwarding.

It is hard (atleast not recommended) to figure out which specific entry is 
affected.
