Description (partial)

Symptom:
Removing netflow from the last/only interface may cause
the ASR1000 series ESP board to reload.

Conditions:
The defect is due to a race condition between the QFP ager logic vs. the
code which processes the ager shutdown administrative action.
If the ager shutdown code executes while the periodic ager function is
executing, the ager function may reuse the timer structure which is
subsequently freed as part of the ager shutdown.
