Conditions

The issue is seen only when an Octane card is present in slot-0 and RSP4-Lite is used. The errors are not seen when the octane card is present in slot-3 or with other RSP's. Also, the issue was confirmed in DT to be happening on 9906 and 9006 chassis where this combination of RSP, LC and LC-slot is present. Other combinations haven't been tried.
