Description (partial)

Symptom:
Chassis non-operational. No traffic passing through ports many port and configuration related commands fail.

Conditions:
Simultaneous failure of multiple npumgrs (including both MIO npumgrs). This can occur when an internal request (e.g., ARP add/del) raises an npumgr assert due to a corrupt npumgr database as npumgrs operate in lockstep.
