Description (partial)

Under very specific conditions, ISIS process may unexpectedly restart when NSR configuration is removed and re-added back.

The problem may only happen when all these conditions are met:
- nsr configuration is removed together with all the address family related configuration (including interfaces)
- the configuration is replayed back quickly, before the garbage collection has a chance to run
