1. In case of redundant supervisor, You can switchover to standby supervisor.

2. This seems to be your standby SUP or you can reload sup.

3. open TAC case for any bug.

This is the bug CSCvf36683:

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvf36683/?reffering_site=dumpcr

This bug is seen on N7K-SUP2/2E where the system is up for a long time. For fixing it you can take a Maintenance Window to do a reload of the SUP.
