If intra-chassis failover is triggered in a loaded chassis, the tmm crashes in some cases of GY reporting


Slot reboots. May trigger more hash rearrangement. Traffic disrupted while tmm restarts.


-- Failover is triggered, -- The daglib hash redistributes the subscriber DATA to different slots. -- Existing flows continue on the slots that were allocated using the old hash of daglib. Note: This is a rarely encountered issue that occurred in a setup with 8 slots and 750 thousand subscribers.
