Description (partial)

Symptom:
After MIO swo vpnmgr crashes and connectivity is lost to the chassis.  Only way to recover is power cycle or by backing off traffic.  Once traffic is bakced off far enough both TACACS login and local login are available via console or mgmt interface.  DPCs look to still forward traffic after the crash on MIO.

Conditions:
Looks like it is only triggered after MIO swo with simulated SGi network outage (ASR is missing it's SGi routes, but Gn routes exist).  Previous connectivity was stable during DPC migration and under regular call-model load.
