Conditions
SC reloads occur during normal router operation
Workaround
None at this point in time
Further Problem Description
- DDTS is raised to track occurrences and provide future enhancements
- Impact is minor since in most NCS55xx deployments consist of redundant SC cards
- CSCwf86232 was subsequently raised to provide enhanced debugging and a debug SMU to be installed at customer nodes for output collection during unexpected SC reload events.
