Under some HA scenarios, the subscriber session will be lost. If such a deleted session is added (the same subscriber-id), the addition attempt fails.


A set of subscribers lost during HA will never be added back.


Intra-chassis HA is configured. One of the blades goes down & comes back up very rapidly & some subscriber sessions are lost. An attempt to add the lost subscriber again fails.


No workaround.
